Oracle has recently released Oracle Enterprise Repository (OER) 12c and Oracle API Catalog (OAC) 12c.I am particularly exited on the latter as it aims to simplify management of APIs and promises to be able to create catalog of your services and APIs rapidly. Furthermore, although OER 12c maintains the same richness as in OER 11g, this product is targeted to advance users that are in need to address more complex governance requirements whereas OAC it’s a light-weight version...

Last week I presented at the  UKOUG’14 conference on instrumenting, analyzing, & tuning the performance of Oracle ADF applications. Instrumentation refers to an ability to monitor or measure the level of a product’s performance, to diagnose errors and to write trace information. Instrumenting gives visibility and insight of what is happening inside the ADF application and in the ADF framework (what methods and queries are executed, when and how often). These runtime...

With the release of Oracle Enterprise Repository 12c another product was released. Oracle API Catalog 12c (OAC) allows you to build a catalog of your organization APIs. OAC provides a layer of visibility to those APIs so application development knows what and which one to use.  OAC includes a simple metamodel for an API asset, automation to populate OAC, and the ability for users to search OAC for APIs and understand the details of the APIs to assess their fit in the user’s...

The validation of required fields in web applications is important, and you have to do the same for mobile applications. In this post I will show how you can validate required fields in Oracle MAF 2.0. To do this, I will use the application of this post: REST/JSON in MAF. Download the sample application: MAFValidationApp.zip. Open empEdit page. Add the Validation Group component to validate required fields.Go to Components panel > Operations, drag the Validation...

Thanks for the nice API management introduction: Installing API Catalog Using the API Catalog for harvesting SOA service APIs Using API Catalog for harvesting Service Bus APIs developer - Users with the developer role have the ability to search OAC for published APIs from the OAC console or using the Oracle Enterprise Repository JDeveloper plug-in. The developer can examine the API metadata to better understand the API. The developer also has the ability to declare interest in...

In this tutorial, you use Oracle JDeveloper and Oracle MAF to build and deploy a mobile application. The application uses a simple Java class to store the data and displays a list of employees on one page and a graph of salaries on another. As you build the application, you will add MAF layout components to further control and customize the behavior of the application. In Part 2 of the tutorial, you add specific device integration to your application. In Part 3, you add a...

Request access to our middleware demo systems here Using an order management scenario, we show how to use Oracle Mobile Suite to integrate with Oracle Applications (EBS in this case). The use case is order management for a sporting goods manufacturing company that provides its mobile sales force with real time access to the backend EBS data as well as business Key Process Indicators (fulfillment accuracy, backorders, order status). Highlights Develop using Mobile Application...

REST/JSON has several advantages over SOAP/XML, so it is preferred for mobile web services. As REST/JSON is a smaller than SOAP/XML, you will be passing much less data over the network. For mobile devices, it is a very important point. In this post we will create a CRUD of employees in Oracle MAF 2.0 using REST/JSON. I will use this REST application (Expose ADF BC as RESTful Web Service). Download the sample application: MAFRESTJSONApp.zip. Initialize the REST Web Service. Creat...
