Orchestration with Fn Flow by Vardan Grigoryants

  The times, when developers built the applications on a single database are certainly long over. Many services nowadays use a variety of databases in combination, to power the different aspects of their applications. We are not an exception in that manner for sure :) Recently we have started a new project, where we have to implement our own data reservoir. For sake of good order, we have chosen MongoDB for saving unstructured meta information and PostgreSQL for saving the actual data. For orchestration of data flow between the databases we have finally chosen an open-source container-native serverless platform called Fn Project, which at the time of writing this article had 2 years history, or so. I’ll not go much in details on how to setup Fn Project, to create your own Fn functions for storing in the databases. There is already much information about it. You can try out these tutorials, if you are new in Fn Project. I’ll just focus on orchestration of Fn functions, which problems we have faced with while implementing our data reservoir and how did we solve them. The Orchestration As mentioned we are storing our data across two databases, we use MongoDB in order to store unstructured meta data, and the structured data is stored in PostgreSQL. Due to the nature of our data, the first entry point is MongoDB, we then use MongoDB’s _id as a cross DB foreign key. Our data is supposed to flow like this: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Kotlin and the Java FDK by David Delabassee

As we saw in this post, it is really simple to write and deploy Serverless Kotlin functions using Fn. The Kotlin support is, in Fn, largely based on the Java support and more specifically on the Java FDK. The initial Fn Kotlin support was a bit different than it is today as it was using the kotlinc compiler in a Docker (build) image. That approach has been recently replaced (from CLI 0.4.129) in favor of Maven using the regular Java FDK images. The only real difference between Java and Kotlin is now how the runnable artifacts (JARs) are being built (obviously!) but in both cases, those artifacts are built using Maven. The fact that the Koltin support is based on the Java FDK offers some nice benefits to Fn users developing functions in Kotlin. JUnit support Both Java and Kotlin are using JUnit for unit testing. Kotlin does it via the standard kotlin.test.junit library, it enables to write testing rules in Kotlin. To get you started, a sample Kotlin based rule is automatically created when you initialize a new Kotlin function via fn init --runtime kotlin myfunc. You can then use Maven to unit test this Kotlin function, i.e. mvn test.

Getting started with Fn Project by Peter Jausovec

I am not one of those lucky ones who can simply read a whitepaper/code/docs and can quickly figure out how things work without trying things out in practice. I need to install things, run things and play with them to get a feeling for how stuff works. If I get stuck, that’s when I am going to read the docs and code to see what I am missing. In this series, I decided to figure out how Fn project works, how to run it, use it and even extend it. Fn project is a container native, cloud agnostic serverless platform. The Basics — install and run This section goes through installing the Fn server, starting it and then creating a simple function and invoking it. You will need Docker on your machine in order to run Fn and once you have that, you can install the Fn with brew: Read the complete article here.

Configure and test your ADF REST Resource by Jeroen Rijnboutt

In my previous post I showed the steps you have to take to create your first ADF REST resource. You can find it here: First steps with REST services on ADF Business Components. I will continue my exploration in the world of ADF REST. We are now going to configure the URL and test the new service. After you run your application, you will see the endpoint in your JDeveloper log: The first thing you will probably notice is the structure of the URL and there is little chance you will like it. Let’s change that first. There are two parts of the URL that can be configured, the Context Root (EMP-RESTWebService-context-root) and the URL pattern (/rest/). The Context Root can be set in the Project Properties of the RESTWebService project. Open the properties and go to the Java EE Application tab. It shows an input field for the Java EE Web Context Root and you will recognize the name from your service URL. Choose a relevant and general name. It will be used for all your services. The URL pattern is configurable in your web.xml file. This file is part of the RESTWebService project. Open it and go to the Servlets tab. Select the only Servlet in the list and open the sub tab Servlet Mappings. Here you can choose your own URL pattern. If you don’t want any pattern, you can enter: ‘/*’.

Oracle Offline Persistence Toolkit - Controlling Online Replay by Andrejus Baranovskis

  Few months ago I had a post about Oracle Offline Persistence toolkit, which integrates well with Oracle JET (JavaScript toolkit from Oracle) - Oracle JET Offline Persistence Toolkit - Offline Update Handling. I'm back to this topic with sample application upgraded to JET 5.1 and offline toolkit upgraded to 1.1.5. In this post I will describe how to control online replay by filtering out some of the requests, to be excluded from replay. Source code is available on GitHub. Below I describe changes and functionality in the latest commit. To test online replay, go offline and execute some actions in the sample app - change few records and try to search by first name, also try to use page navigation buttons. You will be able to save changes in offline mode, but if this is your first time loading app and data from other pages wasn't fetch yet, then page navigation would not bring any new results in offline mode (make sure to load more records while online and then go offline): Read the complete article here   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Running WebLogic Server in Kubernetes & Microservices with Helidon.io project–Meetup June 12th 2019 Brussels

  Join Contribute and Oracle for a Developer Meetup in Brussels During this meetup, 2 topics will be presented to you by a product manager of Oracle. Afterwards you will receive an invite to be able to test these solutions on your own pace. Have fun. Running WebLogic Server in Kubernetes Many organizations are adopting Kubernetes as a platform for managing container-based applications and want to leverage Oracle WebLogic Server in these environments. Attend this session to learn the best practices for running Oracle WebLogic Server in Docker and Kubernetes today, including migrating existing applications, developing and deploying new applications, integrating with other microservices, and managing applications on-premises and in Oracle Cloud. See a demo of Oracle WebLogic Server’s Kubernetes operator, deployment tooling and more. You will also be able to learn about the roadmap as well as future plans. Microservices with Helidon.io project Over the past few years, a lightweight container technology called microservices architecture has significantly simplified the runtime infrastructure for applications. Applications don’t need to be developed as monolithic systems anymore. An application that’s designed using the microservices architecture is essentially a collection of simple services. Microservices-based applications are already being developed by companies across the industry. Every day more organizations are moving away from the monolithic application model and switching over to the microservices architecture. The microservices approach simplifies business integration, technology use, and application development by breaking down the big monolith problem to a set of small tasks that can be handled independently. But adopting the microservices architecture requires some changes to the development processes, tools, methodology, and teams.

Workshop: Web Component Development with Oracle JET

The purpose of this script is to show how to put together a CRUD scenario in an Oracle JET application by means of Web Components. You'll start by setting up JSON Server, which is a fake REST server, next you'll set up an Oracle JET application that connects to it and displays its payload, and finally you'll use the Composite Component Architecture (CCA) to create a reusable Web Component for displaying the payload in different modules, interacting with CRUD functionality defined in the application. Tip: Go here to follow a free three week MOOC about Oracle JET: oracle.com/goto/jet. Troubleshooting: If you run into problems, go here for the completed source files: bit.ly/learn-jet-result The application you'll create in this workshop will look as follows: Get the workshop material here.

Tips and Tricks for List of Values in Visual Builder Cloud Service by Shay Shmeltzer

While working on some customers' applications, I ran into a few performance and functionality tips related to list of values in Visual Builder Cloud Service (VBCS). While it is very tempting to use the built in quick start that binds a list to results from a service, in some cases you might want to take a different approach. One reason is performance - some lists don't change very often - and it makes more sense to fetch them only once instead of at every entry into a page. VBCS offers additional scopes for variables - and in the demo below I show how to use an application scope to only fetch a list of countries once (starting at 1:15). I also show how to define an array that will store the values of the list in a way that will allow you to access them from other locations in your app, and not just the specific UI component. The other scenario that the demo shows relates to situations where you need to get additional information on the record you selected in the list. For example, your list might have the code and label but might contain additional meaningful fields. What if you need access to those values for the selected record?

Creating Editable Tables in Oracle Visual Builder Cloud Service by Shay Shmeltzer

A common request I've been getting from customers of Visual Builder is to be able to edit multiple records that are shown in a table. Oracle JET has an editable table sample that shows how to do this in their cookbook, but the translation from the JET approach to the VBCS way of doing things was a bit tricky for some. I recorded a video and included basic instructions showing you how to implement the JET sample in your VBCS application below. Beyond just implementing the UI aspect of the editable table, you also need to define a strategy of when and how you want to save the data from the table back to the data source. In the video below I'm using an approach that is easy to implement, but is probably not the best way to implement this. I loop through all the records and update them back to the data source one-by-one. A better approach will be to keep a list of rows that were changed and only send them to be updated.

Flow Navigation Menu Control in Oracle VBCS by Andrejus Baranovskis

  Oracle VBCS allows us to build multiple flows within the application. This is great — this helps to split application logic into different smaller modules. Although VBCS doesn’t offer (in the current version) declarative support to build menu structure to navigate between the flows. Luckily this requirement can be achieved in few simple steps, please read John Ceccarelli post — Adding a Navigation Bar to a VBCS Application. I thought to go through instructions listed by John and test it out, today post is based on this. In my next posts I will take a look how to replace navigation bar menu structure with something more advanced, for example — menu slider on the left. I think VBCS have great potential as JavaScript declarative development IDE. I see many concepts are similar to other Oracle declarative development tools, e.g. Forms, Oracle ADF. VBCS runs Oracle JET, all you build in VBCS is Oracle JET. Oracle takes care upgrading Oracle JET version in VBCS, I have applied recent patch (by click of the button) and latest JET version is available within our VBCS environment: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Add a CAA component to your VBCs application by Martien van den Akker

At the #PaaSSummercamp, VBCS is on the agenda. We did a few labs from the VBCS learning path. Nice thing is that you can do it yourself as well. One of the main goals of the OracleJET labs yesterday was to introduce you to CCA components. Since VBCS is mostly based on OracleJET (For the UI that is) it should not be too hard to add a CCA component from our OracleJET application into our VBCS application. So actually, I wanted to try just that. If you go to your OracleJET application project, the CCA components are in the ${OJETProjectFolder}\src\js\jet-composites\: First create a zipfile out of the component, just zip the folder: (I like TotalCommander for this).

JET 5.1: How to integrate a chatbot in your JET application by Luc Bors

Recently I have been working on a customer chatbot project. Although it was not a direct requirement, I decided to look into embedding the chatbot in a web application too. You will never know what the future brings. It struck me that is I could not find any blogposts related to this topic. The only thing is a youtube video by Oracle PM (see resources below) describing how to do this. There can be several reasons as why this has not been blogged about: Nobody is doing chatbot integration in a Javascript UI yet. Oracle Documentation is clear enough. It is very simple so why bother blogging. Anyway, despite of any of these reasons, I decide to write a post on this topic, so that at least I can refer to this myself whenever I need it. So here it is: How to integrate a chatbot in your JET application. This post does not go into the details of creating a chatbot, it just explains how to integrate one in you JET application (or any other Javascript application fo that matter). What do you need? For this solution to work, you need to have an instance to Oracle Mobile Cloud Enterprise (OMCe), or Autonomous Mobile Cloud Enterprise (AMCe) in order to use the chatbot functionality. I have access to AMCe and can use the sample CrCPizzaBot. This bot is an example that ships with AMCe (and OMCe ?) Note that the solution described below works with any Oracle Cloud Chatbot. Step one: Download the SDK's To download the SDK's you need to click the downloads link in your Cloud Environment. This will take you to the page that contains all the downloads for Oracle Autonomous Mobile Cloud Enterprise (AMCe).

Chatbots: What time is it? By Luc Bors

Just a short blogpost describing a solution that I needed for the bot that I'm currently developing. This bot has a typical requirement doing different things during office hours and after closing time. As such I need to know when the user is invoking the bot. Here's how I ended up doing this. What time is it? The developer guide has a section on how to use Built-In FreeMarker Date Operations (see resources below). That is a very resource. I started with using the 'now'  variable, combined with date time. That should return me exactly what I want. So in oBotML that looks like: Unfortunately when I use 'now' to get access to the date-time, it will return the date-time of the server that hosts the actual Bot. This means I cannot use that date-time because it is not the correct date/time of the user's location. After doing a bit of research, I found that the profile property enables your bot to recognise a user’s name, local, and local time.

Java programs as native executables: GraalVM is the answer! By Rosanna Denis

TL;DR: •    Using GraalVM Java applications can be compiled into native standalone executables (will be demonstrated). •    Native executables of small Java programs startup blazingly fast, use considerably less resources compared to running on JVM and do not even require the JRE or any other kind of runtime apart from the OS. •    Running Java applications as native standalone executables provides opportunities for lean usage of Java in serverless functions, cloud deployment and microservices. GraalVM, Please Explain GraalVM started over decade ago as a Sun Microsystems research project. It was subsequently adopted by Oracle Labs and has now reached a stage where it can go out into the wild. GraalVM is a polyglot VM, meaning it can run programs in many different languages at faster paces, usually, than the original specialized runtimes. It allows for interoperability between diverse components in distinct languages as well. For more information see their website. GraalVM is stated to be(come) the one VM to rule them all. Sounds promising, right? Well, it is! And it’s in active development, so if it’s not perfect yet, you can wait for it to shortly provide what you need! Java Moving in a Forward Direction Java is a considered a heavy language – meaning that it is resource intensive. Applications are large – on disk and in memory – and startup time is drawn-out. Already improvements have been made in the newer versions of Java, such as the modular Java runtime (Java 9) and the currently experimental ahead-of-time compiler (jaotc, using Graal) tool in Java 9 (based on JEP 295). Now with GraalVM it’s possible to convert a Java application into a standalone native executable that does not need a Java runtime at all. Read the complete article here.

WebLogic 2c: Solving invalid template error by Martien van den Akker

One of the labs in our Weblogic Advanced Administration 12c course is about using domain templates. When revising the particular lab, we created a domain in Weblogic 12c and then created a template based on the domain. On recreation of the domain based on the template we get an exception: This we get regardless of if we provide nodemanager details at the initial creation of the domain. We did some investigation and found for instance this forum,  that gave a hint, but not a solution or workaround. One important hint is the message 'config-nodemanager.xml: failed to parse the template!(/home/rcma/rcma_domain_template.jar): Parsing the config-nodemanager.xml failed!'. So it relates to the nodemanager configuration and the contents of the config-nodemanager.xml file in the template. By the way, my colleague found that the same issue can also be experienced during pack and unpack, as desribed in Oracle support note 2311027.1. Here you can find that the problem in the config-nodemanager.xml is about the password. If you have a nodemanager password set in the domain's config.xml, it is encrypted with the domain's seed/salt. It can't be decrypted and read by the domain configurator or unpack tools, because they don't have the salt of the source domain. So, what is the work-around or solution? I see two: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Creating a Function from a Docker Image

This tutorial walks through how to use a custom Docker image to define an Fn function. Although Fn functions are packaged as Docker images, when developing functions using the Fn CLI developers are not directly exposed to the underlying Docker platform. Docker isn’t hidden (you can see Docker build output and image names and tags in routes), but you aren’t required to be very Docker-savvy to develop functions with Fn. However, sometimes you need to handle advanced use cases and must take complete control of the creation of the function image. Fortunately the design and implementation of Fn enables you to do exactly that. Let’s build a simple custom function image to walk through the process. As you make your way through this tutorial, look out for this icon.   Whenever you see it, it’s time for you to perform an action. Prequisites This tutorial requires you to have both Docker and Fn installed. If you need help with Fn installation you can find instructions in the Install and Start Fn Tutorial. Getting Started Before we can get starting there are a couple of configuration steps to take care of. Login to Docker Hub To make it possible to push images you need to authenticate yourself with your Docker repository (default is Docker Hub). docker login NOTE: Depending on how you’ve installed Docker you may need to prefix docker commands with sudo. Start Fn Server Next, if it isn’t already running, you’ll need to start the Fn server. We’ll run it in the foreground to let us see the server log messages so let’s open a new terminal for this. 1. Define the FN_REGISTRY environment variable to point the Fn server to where it should pull function images from. If using the default Docker Hub registry you just need to specify your docker user id: Read the complete article here   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Kotlin and the Java FDK

As we saw in this post, it is really simple to write and deploy Serverless Kotlin functions using Fn. The Kotlin support is, in Fn, largely based on the Java support and more specifically on the Java FDK. The initial Fn Kotlin support was a bit different than it is today as it was using the kotlinc compiler in a Docker (build) image. That approach has been recently replaced (from CLI 0.4.129) in favor of Maven using the regular Java FDK images. The only real difference between Java and Kotlin is now how the runnable artifacts (JARs) are being built (obviously!) but in both cases, those artifacts are built using Maven. The fact that the Koltin support is based on the Java FDK offers some nice benefits to Fn users developing functions in Kotlin. JUnit support Both Java and Kotlin are using JUnit for unit testing. Kotlin does it via the standard kotlin.test.junit library, it enables to write testing rules in Kotlin. To get you started, a sample Kotlin based rule is automatically created when you initialize a new Kotlin function via fn init --runtime kotlin myfunc. You can then use Maven to unit test this Kotlin function, i.e. mvn test.

Developing FaaS with Oracle fn Project by Carsten Wiesbaum

In my last post I wrote about general concepts behind Function as a Service (FaaS) and my view on this application development style. As an example I used the basic pipes and filters concept implemented by Unix Shells and many shell commands. Within this post I will use the same example and implement it using a Function as a Service platform. To recap the scenario, we had a simple JSON file containing booking records. From this file we identified certain records based on purchased products. Afterwards we extracted customer emails which could be used as a list for targeted marketing. The FaaS platform I will be using is Oracle fn Project. It is an Open Source project which aims to develop an open and standard based FaaS Platform as alternative to mostly proprietary solutions existing in the market today. According to Oracle a managed service will be released in near future. Let us start and develop FaaS with Oracle fn Project! Developing FaaS with Oracle fn Project To begin with, the beauty of fn Project is that one is able to develop FaaS applications on any machine. This includes local development machines. From the decision to use fn to the first deployed function one needs less than nine shell commands. The mandatory „Hello World“ example can be found on fn Project’s GitHub repository. Just follow the instructions and come back to this post with a running fn server. Now let us start to implement our FaaS example using fn Project. The first function should extract all booking records containing a specific product. Let us call this function searchProduct..

Adding missing extensions to JDeveloper 12.2.1.3 by Timo Hahn

  The current version of JDeveloper 12.2.1.3 is missing some extensions which are popular in the older version of JDeveloper. One of them, which is asked for a couple of times, is the MAF extension. Other extensions like ‘BI ADF ViewRegions’ are missing too. Here are the images from the update page of JDeveloper 12.2.1.3 As you see, there is no ‘Mobile Extension’. In general, you have two options to get the missing extensions installed: 1. Download the extension from the ‘Extension Exchange’ and install it from a local file 2. Add the ‘Extension Exchange’ to the known sources of extensions and load the extension right from JDeveloper Personally, I prefer the second way as it only shows the extensions available for your version of JDeveloper. You can only install extensions which are configured for your version anyway. Extension Exchange on the WWW You’ll find all extensions available for all version of JDeveloper on the public ‘Extension Exchange’. From there you can download an extension and install it in JDeveloper from the local file. When you download an extension make sure to load the right version as you can only install extensions which are configured for your version (check the min and max version of the extension!).

ADF Postback Payload Size Optimization

Learn how to improve performance by having ADF requests send HTTP requests only for changed values, speeding up the server. by Andrejus Baranovskis Recently, I came across a property called oracle.adf.view.rich.POSTBACK_PAYLOAD_TYPE. This property helps to optimize postback payload size. It is described in ADF Faces configuration section A.2.3.16 Postback Payload Size Optimization. ADF partial requests execute an HTTP post with values from all fields included. When the postback property is set to dirty, it will include only changed values in the HTTP post. As result, the server will get only changed attributes. Potentially, this can reduce server time processing and make the HTTP request size smaller. This can be especially important for large forms with many fields. Let's take a look at an example. After clicking on any button in the form, go to the network monitor and study the Form Data section. You will see IDs and values for all fields included in the UI. All fields are submitted with an HTTP request by default, even if these fields were not changed: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Blockchain in a Fish Bowl Oracle Developer Meetup May 13th Cologne Germany

  Join esentri and Oracle for a Developer Meetup in Cologne   Der Hype um die Blockchain Technologie hat sich etwas abgekühlt, die Technologie ist aber nicht minder relevant. Nach unserer erste Runde zu diesem Thema, wollen wir uns dieses mal mit konkreten Erfahrungen bei der Umsetzung von Blockchain Use Cases auseinander setzen. Wir werden den Abend mit einem Erfahrungsbericht starten. Anschließend werden wir eine Fish Bowl Diskussion mit Teilnehmern durchführen. Agenda 18:30 – 18:45 Begrüßung 18:45 – 19:15 Dezentraler Rohstoffmonitor (Ingo Sobik, Tim Rüb) 19:15 – 19:30 Umbau + Verpflegung 19:30 – 20:15 Blockchain in a Fish Bowl 20:15 – 21:00 Networking Monday, May 13, 2019 6:30 PM to 9:00 PM   esentri AG Burgunderstraße 26 · Köln     Dezentraler Rohstoffmonitor – Smart Contracts für den Handel Bedingt durch Preisschwankungen an den Rohstoffmärkten ändern sich für Produzenten die Herstellungskosten ständig. Damit diese Veränderungen im Rahmen von Verträgen zwischen Produzenten und Händlern eingepreist werden können, müssen die Verträge regelmäßig an aktuelle Rohstoffpreise angepasst und Preise für Produkte neu verhandelt werden. Dies ist oftmals mit einem erhöhten manuellen Aufwand verbunden. In unserem Projekt haben wir es uns zum Ziel gesetzt diesen Aufwand zu reduzieren, indem wir den Verhandlungsprozess zwischen Hersteller und Händler automatisieren. Hierzu haben wir eine prototypische, dezentrale Vertragsplattform mit eingebautem Rohstoffmonitor entwickelt. Kaufverträge zwischen Händlern und Produzenten werden als Smart Contract direkt über die Plattform abgeschlossen. Besonders dabei ist, dass Preise für die im Produkt verarbeiteten Rohstoffe dem Smart Contract durch den Rohstoffmonitor zur Verfügung gestellt werden. Verändern sich Rohstoffpreise zwischen zwei Bestellungen wird der Produktpreis automatisch entsprechend angepasst. Eine weitere Besonderheit ist die Manipulationssicherheit, die das System durch den Einsatz einer Blockchain erhält. Dadurch, dass keine der Parteien, weder Händler noch Produzent, volle Kontrolle über Bestellungsdaten oder Preisinformation besitzt, können diese nicht ohne gegenseitiges Einvernehmen verändert werden. Dadurch gewährleistet unser System vollste Transparenz bei gleichzeitig höchster Datensicherheit. For details please visit the registration page here. For additional local Meetups please see here.

So as soon as the user press this button it’s text should be changed to ‘Processing..’ and after the upload is complete it should be ‘Done’, First I have tried it using java means in same button action listener but in this case, button text was changed only after event processing is complete So for this purpose, I have used some javascript function, this is quite simple (see the implementation) Drop a button on the page and create an ActionListener, it will change the button text to ‘Done’ after event processing (used Thread.sleep() for some long processing).

ADF Applications – Download DVT Charts in ADF 12c (and other technologies) by Pedro Curto

As we mentioned in past articles ADF 12.2.1 comes with several corrections of customer-reported and internal (unpublished) errors, along with new features that can be useful when developing applications. Recently we worked with ADF Visualization Components and we faced a big problem: there is no easy way to export a rendered DVT chart! After doing some research in Oracle community and blogs we found that for ADF 11 there was one way: link Unfortunately for ADF 12c the DVT class hierarchy was changed, and the previous method could not be used anymore. We did not find a way of using ADF classes to export the charts. The only suggestion was to use the <af:printablePageBehavior> to print the page. However, this will not fulfill the client’s needs so we had to try other ways. With all these facts in consideration, we chose using JavaScript in order to export the charts generated by ADF. To clarify any misleading concepts, ADF charts are rendered as Scalable Vector Graphics (SVG). This article will present a generic way to export and download the Scalable Vector Graphics as an image using JavaScript. In other words, the method presented can be used with ADF but also with other Application Development.

Debugging your JET Command Line Build Scripts By Duncan Mills

  The JET ojet command line tool provides you with a bunch of helpful capabilities ranging from scaffolding applications through to running them.  One of the features that I use extensively is the ability to decorate the build and serve functions with custom hooks. If you are not familiar with this feature have a look in the /scripts/hooks folder of your JET project and you will see a set of after_* and before_* javascript files that will be run when you issue a command such as "ojet serve web". The default implementation of these hook scripts are empty but they are there for you to carry out any extra tasks that you might want to complete as part of the standard build or build-serve processes. For example you might want to automatically package your /web output directory into a WAR file every time that you do a release build so that you can then deploy that artefact to an application server. Now, as with any programming, it’s just possible that you might make a mistake and need to be able to debug these hooks scripts.  There is only so much that you can do with console.log() after all!  I use these ojet hook scripts a lot (and occasionally make mistakes), so I though that I’d share my setup for effectively debugging them.  I’m going to explain how to do it, based on my O/S and preferred editing environment for write node code. I’m not telling you that this is the "correct" way to do it, other IDEs and editors are available and of course details will differ from O/S to O/S. However, you should be able to apply the same principle to your chosen combination of O/S and editing environment. Debugging in My Setup My preferred environment is OS/X and the editor I use for node javascript is Visual Studio Code, a good all around editor for this kind of thing.  Visual Studio Code is super easy to configure for node debugging and debugging the ojet-cli.

JET Custom Components XXII – Template Slots by Duncan Mills

  In JET 5.1.0 we introduced a really exciting and useful addition to the component authors toolbox, that of templated-slots. Before I dive into the mechanics though, I’d like to discuss the kind of problems that they are designed to solve: It’s All About Scope If you have used normal slots, you will be aware that the intent is to allow the component author to leave placeholders in the component view for consumers to drop in their own content.  The typical example of this being something like a toolbar component which supplies a certain set of pre-ordained buttons, but which supports a slot for consumers to add some of their own.  So slot content is supplied by the consumer but "managed" from a layout perspective by the component. This is all very good, however, there is one restriction that can limit the usefulness of slots and that is the matter of data scoping.  Any components that you put into a slot may well end up as children of the custom component in UI / DOM terms, however, in data binding terms they are peers of the custom component. The slotted components cannot see the data that the CCA is managing internally and are effectively bound to the same parent viewModel as the custom component is.  This makes it tricky for the custom component to manage data in the slotted children and often results in compromised component design just to enable such data sharing to take place. The other big problem area with conventional slotting and the scoping rules surrounding it, is the creation of custom components that use stamping user interfaces to output sets of data. An example of such a component might be a customized list-view  where the custom component is managing the communications with a REST endpoint that is providing the data, however, you, as the component author, want the consumer to have the ability to shape how each row should be rendered as it’s stamped out.  With conventional slotting, this type of use case is really not possible without cheating1 and this is really why templated slots have been introduced.

Managing Visual Builder Code with Developer Cloud Service by Shay Shmeltzer

Developer Cloud Service (DevCS for short) is a foundation service in the Oracle Cloud that provides you with a full cloud platform to manage agile development processes and automate DevOps cycles. It is available for every Oracle Cloud customer. One key capability (that is actually offered for free as part of your Oracle cloud subscription) is Git based repositories that you can create to manage the code of your application. In this blog we are going to show you how to leverage Visual Builder's built in integration with DevCS to manage your code lifecycle in these Git repositories. A full introduction to Git and the way you work with it - specifically the gitflow approach to code management is outside the scope of this blog. But since Git is the most popular version management solution out there - you can find many internet tutorials that will teach you how to implement these methodologies. With the git integration in VBCS developing application in teams with multiple developers and multiple tasks is much more organized. In addition you have a full view of the code changes in your application and the ability to easily manage versions. In the video below we teach you some of the basic steps including: · Creating a DevCS project with a default Git repository · Connecting VBCS to DevCS and to a specific Git branch · Pushing code into the repository · Creating branches · Pulling and importing code from repositories · Viewing code changes in DevCS · Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

How-to Build Card Layout Responses from Custom Components by Frank Nimphius

Using the Common Response component (CR component) in Oracle Intelligent Bots, bot conversation designers can build arbitrary complex bot responses declaratively. A very popular bot response is the card layout that displays multiple cards in a vertical or horizontal order with each card displaying a title, a description, an imagen an optional URL and one or more action items for the user to tap on. While the recommended conversation design strategy is to use the CR component whenever possible, there exist use cases in which a custom component must render its own UI. Still displaying data in cards remains a popular layout. In this article I explain how to display a card layout from a custom component  and how you handle post back actions (buttons on a card) and user text entries.  The article also contains the complete code listing of the example used in the article.

How to Ensure Valid User Date Entries in Oracle Intelligent Bots using BotML and a Custom Component by Frank Nimphius

Oracle Intelligent Bots provides a DATE entity that bot designers can use to assign and save dates for later use. Though the DATE entity validates dates by their format, it does not check whether the provided date actually exists. For example, February 29th only exists in leap years and February 30th does not exist at all. Assigning a date of February 30th is saved as March 2nd, which from a logical perspective appears to be the right thing to do, but from a business perspective may not be what you want. Given that enforcing valid date entries is important for many businesses, how can you build chatbots that accept date input only if the date really exist? The use of Regular Expression comes to mind, but this is more for detecting valid patterns than a logic that includes leap years and different days in a month. If you cannot use Regular Expressions then the solution obviously needs to be found in JavaScript. A benefit of a JavaScript based solution is hat JavaScript is the programming language of custom components in Oracle Intelligent Bots. In this article I explain how to create a custom bot component that validates date string entries based on a pre-defined date format and the validness of the actual date. If the date input string has passed validation you can then use the System.MatchEntity built-in component to save the date object in a context variable. Once saved in a context variable, using Apache FreeMarker expressions, you can print the date in any format you like. Sounds interesting? Well it is.

How-to Populate Radio Groups, Checkboxes and Lists in Instant Apps with Data Collected in Oracle Intelligent Bots By Frank Nimphius

Instant apps are micro applications that you call from a bot and that open in a web view on the mobile device or a tab on a browser. Technically, instant apps are server side applications that are called from Oracle Intelligent Bots in the context of a bot conversation and that can receive parameters from a bot and return parameters back to it. What's really cool about instant apps in the context of a bot conversation is that they provide functionality consistently across messengers  that otherwise may not even be available in specific messengers. For example, instant app features provide you options to render charts, upload photos, capture signatures, embed and communicate with remote websites, integrate YouTube and social buttons, display PDF documents and many more. In this article I explain how data information can be passed from a bot in Oracle Intelligent Bots to an instant app and how this data can be used to render a list, a group of radio groups in my example, for the user to select from. The selected value is then passed back to the bot.

Bots : What do YOU need to look for when choosing one by Soham Dasgupta

  Chatbots are now the new craze in the market. Almost everyone is fascinated by them and everyone is trying to have one for their enterprise. Since the day I started working with Bots, which is merely 1.5 years ago, there has been a lot of different tools, platforms, technology released to the market. Chatfuel, DialogFlow, Botsify, Motion.ai, Wit.ai etc, the list goes on and on. Not only small startups but even Microsoft and Oracle has come up with their own cloud based Bot development platform. In only this limited amount of time, the number of innovation in this area is truly amazing. So as a Chatbot developer and promoter, I have a lot of choice, but at the same time, which one is the best? Which platform I should propose to my client? Which is the best fit to the needs my customer has? It is not only difficult, but very challenging to judge these platform and/or tools. So, my advice, to you, would be ask a few simple questions about the platform/tool. Check with you use-cases, requirements, needs. Before you choose one.

Function as a Service (FaaS) by Carsten Wiesbaum

  In the last few years lightweight and flexible technologies and architectures become the predominant approach for enterprise applications. Besides Microservices, Function as a Service (FaaS) or Serverless Programming is a commonly discussed topic. Some see FaaS as an addition to today’s lightweight architectures, others see it as next step within the evolution of Cloud and IT. Throughout the last few months I had many interesting discussions regarding FaaS and recognized that many people have problems to understand underlying concepts and identify useful use cases. As result I want to share my thoughts about this topic within a blog series. Within this article I want to share my understanding of FaaS and why I, as an architect, see it as valuable addition to solve certain problems. To support my argument, I will present an example using a technology most people would not expect when reading about FaaS. In the second article I will reuse my example and show an implementation using Oracle’s fn project, an open source FaaS platform. Finally, in the third article I want to show how to combine fn project functions to solve more complex problems. Functional Programming First of all, let us talk about functions. In my opinion functions have the following basic characteristics: Clearly defined input Clearly defined action which they execute based on the input Clearly defined output Are idempotent, meaning using the same input several times results to the same output each time I execute the function Let us explain these characteristics using an example.

Why did you choose Knockout and other libraries over more popular ones? One of the main objectives of Oracle JET was to be a modular toolkit that allows developers to use as little or as much as they need for their particular project. To accomplish this, we researched the best JavaScript libraries for specific tasks needed when developing a modern JavaScript client-side application. While there are plenty of more popular full frameworks available, we felt that with the rapidly changing JavaScript landscape, tying developers into one specific framework was not in the best interest of future growth and flexibility.

Some Tips for Working with Visual Builder UI Components in Oracle Integration Cloud by Siming

Introduction Oracle Integration Cloud Service (OIC) has now bundled several formally independent PAAS services into a single cloud service. One of these bundled services is Visual Builder (formerly VBCS). The 18.2.5 release of Visual Builder in OIC is more user friendly than prior releases. For example, in 18.2.5, users are not forced to write Javascript code to create a custom data type, and data mapping can be done with drag and drop. This release of Visual Builder also includes enhancements for Process application integration. While creating some test cases to demonstrate Process integration in Visual Builder, I encountered a few issues in working with some UI components. I would like to use this post to share some tips and work-arounds for these issues that might be helpful to other OIC developers working with Visual Builder. Action Chain can be defined at application, flow and page level Action chains can be defined at all three levels – application, flow, and page.  The chains defined at parent level can be used by the chains at sibling or child levels. The following pictures show action chains created at application, flow and page level respectively. The following picture shows a page action chain that uses a Call Action Chain action to call a chain defined at flow level (parent) and application level (root level). Leveraging this feature, we can define chains once at a higher level and share them with all child flows and pages. In this example, we created three common action chains at the application level. They perform navigation functions to previous page, to another flow, and to another page in a flow. These functions are frequently used in all parts of a web application.

Custom JavaScript Client Code in Oracle Visual Builder by Andrejus Baranovskis

Hey, this is my first post about VBCS, you should expect more posts in the future about this topic. Red Samurai decided to choose VBCS as our primary JavaScript development IDE in the cloud. We are going to use it for declarative JS development, similar as we use JDeveloper for ADF. I was going through the custom JS client code functionality in VBCS and thought it would be good idea to describe how it works. There is good material available for the same topic from Oracle, I recommend to go through it - Variables, Modules, and Functions, OH MY! Custom Client Code in Visual Builder.

Creating Dependent/Cascading Select Lists with Visual Builder by Shay Shmeltzer

A common requirement in applications is to have dependent lists (also known as cascading lists) - meaning have the value selected in one place influence the values that could be select in another place. For example when you select a state, we'll only show you cities in that state in the city list. In the short demo video below, I'm showing you how to implement this cascading lists solution with the new Visual Builder Cloud Service. The solution is quite simple You catch the event of a value change in the first list, and in the action chain that is invoked you set a filterCriterion on the second list. (See this entry for a quick introduction to filterCriterion). Since the list is connected to a ServiceDataProvider, there is no further action you need to take - the change to the SDP will be reflected in the UI component automatically.

How-to add the user query string to the Q&A optionsLabel property on the System.Intent component by: Frank Nimphius

What this quick tip is about Finding a good title for this quick tip is probably harder than to explain the solution. So allow me to use what feels like a thousand words before showing you two images that support my point. In Oracle Intelligent Bots you can configure the System.Intent component with Q&A so that the user query not only gets processed by the intent engine but also passed on to the Q&A feature. In a perfect scenario the user query is clear and points to either an intent to be resolved and handled by the intent engine or a question handled by the Q&A feature. Often it may happen that both, hen intent engine and the Q&A feature, find a match for the user query. Then, depending on the System.Intent component configuration, Oracle Intelligent Bots shows a list for the user to either select and execute the intent, or display the Q&A feature to select an answer. The following System.Intent configuration is what you get when you select the "Intent with Q&A" template from the "+ Component" button option in the dialog flow editor. Note that I removed properties that are not relevant for this quick tip.

Building Complex Bot Responses with Ease by Frank Nimphius

Learn to love the common response component and render complex and composite responses. The Oracle Intelligent Bots feature of Oracle Mobile Cloud Enterprise uses built-in components to render bot responses in a dialogue flow. Being component-based is an advantage Oracle Intelligent Bots has over its competitors, because it enables bot designers to easily build bot conversations with no code. The common response (CR) component is a relatively new component in Oracle Intelligent Bots that can render arbitrary complex and composite responses, thus making it even less likely that you’ll need to write code. About the Common Response Component With the rise of chatbots, messaging channels such as Facebook Messenger, Slack, and WeChat have become the equivalent of operating systems in client/server computing. Also like operating systems, whereas all messaging channels do the same things, they differ in the UI they can render, the functionality they support, and the message structure—the payload—they require. The CR component, like the Oracle Intelligent Bots list and text components, is built on top of a new channel-agnostic message model in Oracle Intelligent Bots that abstracts the channel specifics from component developers. For component developers, this new message model means that they can worry less and be more productive.

University of Adelaide employs chatbot to handle ATAR score queries by George Nott

The University of Adelaide has piloted a chatbot to handle the tsunami of enquiries that come at the end of the academic year from prospective students regarding ATAR bonus points. The Oracle, cloud-based bot – implemented by Rubicon Red – was trialled late last year and led to significant reduction in telephone calls to the university’s six-person admissions team. A student’s ATAR (Australian Tertiary Admissions Rank) is a score between zero and 99.95 that tells you where you rank in your year group. It is based on their HSC results with different weighting given to various subjects, and the figure is a percentile position relative to all the other students in their year. Universities set a minimum ATAR value for each course. Students may be eligible for adjustment (or bonus) ATAR points. There could be adjustment points added to the ATAR scores of students that do well in HSC subjects relevant to their desired university course; if their school is in the vicinity of the university or a regional area; or if they have been affected by disrupted schooling, financial hardship, illness, disability, refugee status or socio-economic disadvantage.

Oracle Mobile Cloud Enterprise by Carlos Chang

If you’ve been reading this blog lately, you know we are in the early innings of artificial intelligence (AI). It’s good to see Oracle at bat, and having an early lead leveraging AI and machine learning (ML) within an enterprise environment. Following up on the ground breaking release of Oracle Autonomous Database in March and then the first set of Autonomous Cloud Platform Services  that included Analytics Cloud, Integration Cloud and Visual Builder (May 7th), it’s exciting to be part of the next wave of services that includes the Mobile Cloud - which by the way, includes Intelligent Bots! Do you recall the very first release of Oracle Mobile Cloud Service back in Sept 2013? Since then, the product has garnered market leadership position, customer accolades, and named leader by highly regarded analysts including Gartner, Forrest and Ovum. As Oracle is going all-in with mobile and cloud, it’s only fitting these waves of innovative releases, Oracle is all in on AI. Lets touch on a couple of cool new features for this release. QnA Builder - take your standard frequently asked questions document, import it into QnA Builder, and automagically create a chatbot to serve those needs. No more expecting customers to read an FAQ, or wasting valuable staffing resources responding to the same, repetitive questions. Let the chatbot deal with that - 24x7, 365 days a year! And if the chatbot gets out of its depth of knowledge (we are not yet at the level of singularity - no one is) we’ve built in a bot-to-agent handoff, to better serve your customers, while scaling up operations. Just as machinery made people more efficient, so will AI-driven chatbots. AI and chatbots are the future, and Oracle is taking that out of the lab and into the enterprise. Just ask Exelon, Bajaj Electricals, or the University of Adelaide and they’ll gladly laude the benefits of chatbots!

Read all your WebLogic Data Sources in a Click! by Vijayalakshmi Karupusamy

The FlexDeploy WebLogic plugin provides operations to automate the management of domain configurations. These operations are driven by using property files from Source Control System such as Git or SVN. This process makes it easy to manage WebLogic configurations. The WebLogic plugin has a new operation to read all Data Sources from WebLogic Domain and write them into property files. This helps to reduce the manual efforts required for extracting data sources from domain and generating property files as input for one of the existing automation operation. (See Save Time and Headaches – Automate Your WebLogic Data Source Configurations for more details on the WebLogic plugin.) Let me show you how it works: See a very simple Data Source configuration deployed in WebLogic Domain as below. This Data Source will be retrieved and stored into a property file as below, which will be used later during the WebLogic domain initial setup across environments.

Serverless Native Java Functions using GraalVM and Fn Project by Leonardo Zanivan

  GraalVM: a game changer for Java and Serverless? TL;DR;   Java Functions compiled into a native executable using GraalVM reduces cold start times and memory footprint by order of magnitude compared to running on JVM. Native Java Functions performs equal to or better than Go functions in terms of execution time and memory used. Native Java Functions executable runs from scratch base image, thus have a similar size compared to Go executable images.   Source code is available at https://github.com/panga/fn-native-java panga/fn-native-java fn-native-java - Fn Project Native Java Function using GraalVMgithub.com What's GraalVM? GraalVM is a High-performance polyglot VM open sourced by Oracle and currently in active development. It also has the ability to compile JVM languages and a few other languages like JS, Python, Ruby and R into native executable. Some examples are demonstrated in @graalvm blog. The executable actually runs in a optimized native VM called "SubstrateVM". Although is quite stable nowadays, it still contains some limitations that are currently being worked on and can be released in near future. What's Fn Project? The Fn Project is an open-source container-native serverless platform that you can run anywhere — any cloud or on-premise. It’s easy to use, supports every programming language, and is extensible and performant. It is an evolution of the IronFunctions project from iron.io and is mainly maintained by Oracle. So you can expect enterprise grade solution, like first class support for building and testing. It basically leverages of the container technology to run and you can get started very quickly, the only prerequisite is Docker installed.

Traffic routing between functions using Fn Project and Istio by Peter Jausovec

In this article, I’ll explain how I implemented version based traffic routing between Fn Functions using Istio service mesh. I’ll start by explaining the basics of Istio routing and the way Fn gets deployed and runs on Kubernetes. In the end, I’ll explain how I was able to leverage Istio service mesh and its routing rules to route traffic between two different Fn functions. Be aware that the explanations that follow are very basic and simple — my intent was not to explain the in-depth working of Istio or Fn, instead I wanted to explain enough, so you could understand how to make routing work yourself. Istio routing 101 Let’s spend a little time to explain how Istio routing works. Istio uses a sidecar container (istio-proxy) that you inject into your deployments. The injected proxy then hijacks all network traffic going in or out of that pod. The collection of all these proxies in your deployments communicate with other parts of the Istio system to determine how and where to route the traffic (and bunch of other cool things like traffic mirroring, fault injection and circuit breaking) . To explain how this works, we are going to start with a single Kubernetes service (myapp) and two deployments of the app that are version specific (v1 and v2).

Simply speaking, a micro frontend must implement business logic from top to bottom (database, middleware, and UI) in an isolated environment, it should be reusable and pluggable into the main application's UI shell. There must be no shared variables between micro frontends. The advantage is that distributed teams can work on separate micro frontends; this improves large and modular system development. There is a runtime advantage, too: if one of the frontends stops working, the main application should continue to work. I have implemented micro frontend architecture with Oracle JET. The source code is available in this GitHub repository. There are three applications, two with micro frontends, and one being the master UI shell. Both micro frontends are implemented as JET Composite Components. The first is hosted on WebLogic; it calls the ADF BC REST service in the backend. The second is hosted on Node.JS and returns static data. The first micro frontend implements a listener, which allows handling of actions from the outside.

Microservices Architecture pt.1: Definition by Lykle Thijssen

There is a lot of talk going on about Microservices architecture these days. Since I presented about the subject at the NLOUG Tech Experience this year, I've been getting a lot of questions and comments about it, so I've decided to make a more structured breakdown through a series of blogs. To kick things off, I will explain what Microservices architecture is, which in itself is not that simple. Definition There is no generally accepted definition of Microservices architecture. However, there are some starting points and generally accepted properties that I consider to be valid enough to see as part of the definition. Let's just start with what Adrian Cockcroft, the architect who introduced the concept at Netflix, has to say about it: "Microservices are loosely coupled service oriented architecture with bounded contexts" This pretty much sums it up, but it lacks detail to get a proper understanding of Microservices architecture. So, we need to analyze this sentence and draw some conclusions from it. First of all, mr. Cockcroft is clearly seeing Microservices architecture as a form of SOA, instead of something completely different. Then he goes on to put some limitations on how this SOA should be done:   Loosely coupled With bounded contexts   Why are these aspects so important? First of all, to understand why loosely coupled is so important here, one needs to understand how much SOA applications are built. They mostly rely heavily on reusable business services, a canonical data model and a shared runtime. It's not exactly what I would call loosely coupled, since there are quite some dependencies and the impact of making changes to a service or the runtime configuration can be rather large.

Oracle Cloud Native – deploying scalable isolated functions in the cloud by Léon Smiers

When moving to the cloud, and specifically when moving towards cloud-native applications, different design patterns apply when compared to the more traditional (on-premises) applications. All these cloud-native design patterns and principles have one common denominator – showing emphasis on scalability and function isolation. Where traditional applications used to be developed as big monolith solutions housing a large set of functionalities, the more modern and cloud-native applications are a collection of isolated functions that together form the application. The benefit of the more isolated function design is that each function can be designed and developed in relative isolation from the other functions. The microservices paradigm supports this way of implementing systems by its prime design principles around both function isolation and scalability In a system based on isolated functions, each function must interact with the others to support the system overarching functionality. Usually. no orchestration functionality is available in this architecture. Instead of a system overarching process engine to enable end-to-end functionality, a more choreography approach is used, where the functions themselves are responsible for the execution of a process. Additionally, each isolated function can be scaled up or down by adding more instances of a specific function if required. The need for isolated functionality and the ability to scale isolated functionality is driven by and helps fuel the adoption of microservices. When developing microservices, you will have a rich set of options and almost every modern language provides solutions and functionality to develop microservices (polyglot approach). One of the most favored approaches at this moment is using Java with the support of Spring. Additionally, you see developers and enterprises moving to an approach where each microservice is deployed within a container for obvious reasons.

JDev 12.2.1.3: Creating a shared skin jar (Part 1) by Timo Hahn

In earlier versions of JDev, skins have been created either by pure code or by using the free Skin Editor. However, since JDev 12.2.1.x the skin editor has been integrated into JDeveloper itself. A couple of questions in the ODC JDeveloper space are about how to create a skin with JDev which can be deployed as a shared library to a WebLogic Server. I gave this a try and it turned out, that you can build an ADF library jar from a skin project but you can’t use images to this jar which you might want to use in the application. In this blog, I’ll show how to create a skin with resources like images and how to build a jar file from the skin together with the images and deploy it aa s shared jar to a WeblogicServer. Building a skin project The first part is to build a small skin project. The project we use to create a minimal skin, just to show that the skin is changing something. Then we add some images to the skin which we want to use in the application which uses the skin. Such images can e.g. used on an af:button component.

JDeveloper – Increase Productivity Using Shortcuts by Pedro Curto

Integrated Development Environments (IDEs) are useful tools to maximize productivity for developers. This article will present how to configure new shortcuts and some very important advanced shortcuts available by default in JDeveloper that can be very useful to speed up development process. Introduction and Configuring Shortcuts In order to maximize programmer productivity, one important aspect is the use of some shortcuts. We all know some basic shortcuts like “CTRL+X” (to cut) or “CTRL+C” (to copy) and we use it every day as they save a lot of time. So, essentially, the shortcuts help you work more effectively and speed up almost everything you do. In other hand, long lists of keyboard shortcuts can quickly become overwhelming if you’re just getting started. The key to learn and memorize the shortcuts is to practice every day with a smaller but growing set. In order to help you, I will explain how to see the list of shortcut keys in jDeveloper and, also, how to configure your own. Firstly, to see the list of shortcut keys available in your jDeveloper, you can select “Tools->Preferences…” that will open a window with the “Preferences” of your environment. In that window select “Shortcut Keys” in the left. A list with all the shortcuts available are presented. Read the complete article here.

Oracle ADF BC REST – Performance Review and Tuning by Andrejus Baranovskis

I thought to check how well ADF BC REST scales and how fast it performs. For that reason, I implemented sample ADF BC REST application and executed JMeter stress load test against it. You can access source code for application and JMeter script on my GitHub repository. Application is called Blog Visitor Counter app for a reason - I'm using same app to count blog visitors. This means each time you are accessing blog page - ADF BC REST service is triggered in the background and it logs counter value with timestamp (no personal data). Application structure is straightforward - ADF BC REST implementation: When REST service is accessed (GET request is executed) - it creates and commits new row in the background (this is why I like ADF BC REST - you have a lot of power and flexibility in the backend), before returning total logged rows count: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).
