Introduction To build functional and performant mobile apps, the back-end data services need to be optimized for mobile consumption. RESTful web services using JSON as payload format are widely considered as the best architectural choice for integration between mobile apps and back-end systems. At the same time, most existing enterprise back-end systems provide a SOAP-based web service application programming interface (API) or proprietary file-based interfaces. In this...

This post is about a common questionHow can we populate an af:table programmatically ? It means that data in af:table is not populated through model layer (Using ViewObject) using binding layer. lets say I have some values in our managed bean and have to show records in tabular format on pageSo what we have to do - First you should know the number and data type of columns in table, suppose i have to populate a table for person details (name, mobile number and salary). to get...

In a BPEL process there are some use cases where a Wait activity or the onAlarm branch of a Pick activity is needed. An example for an onAlarm branch is a timeout mechanism for an asynchronous call. These activities save the instance in the dehydration store for a defined time. To wake up the waiting instances there is a quartz scheduler job running in the weblogic and check the expiration date in the dehydration store. For the case the dehydration store is not available, the...

In last some of the posts regarding MDS, we saw how to achieve Personalizations and Seeded Customizations in Enterprise applications using Oracle ADF. There was explanation how to leverage Oracle ADF MDS framework for this purpose. Most of the personalization and customization is provided OOTB by the framework and just requires correct configurations and steps to achieve. These are declarative user customizations which allow to implicit save component changes done by the...

It is my assumption that inbound and outbound emailing has been configured – for example for a GMail account – as described in these two articles: GMail for inbound mail in SOA Suite 12c and GMail for outbound mail in SOA Suite 12c and that test mails can be sent and received. The steps are: configure an email driver for SOA Suite for outbound and inbound emails configure an email address (one of the inbound email accounts set up on the email driver configuration) for...

The Oracle SOA Suite Spring component has been present since SOA Suite 11.1.1.3 (11gR1 PS2). This component allows easy integration of Java code with other SOA Suite components such as (among others) BPEL, BPM and Business Rules. In SOA Suite 12c (12.1.3.0) this component is still present. In This blog post I will provide a short example on how it can be used and how the first problem I encountered with this component can be avoided. Implementation First create a SOA...

Images are heavily used in Mobile apps. For instance a list that contains employees usually shows the images of these employees. This works well when you have a WIFI connection, but what if you are using slower connections ? If you look at a mobile twitter app you will see that, depending on connectivity, images are loaded instantaneously or delayed. In this post I explain how you can load the images of a List in a background process, after the other content has been loaded. As...

Previously I had a post about dynamic ADF attribute binding creation and dynamic ADF form generation - Adaptive Form with Dynamic ADF Attribute Value Binding. Blog reader was asking how to generate dynamic ADF LOV binding using similar approach. This is possible and actually documented in Eugene Fedorenko post here - Dynamic LOV binding. I will use the same piece of code to extend my sample application with dynamic ADF LOV binding support.Here you can download updated...

The Oracle SOA Suite provides an Audit Trail monitor screen where the message flow between the different SCA composites can be tracked. Depending on the audit level, it can provide a very detailed chronology of the different states of the message, including the first component that receives the messages, its correspondent transformation along the way, and the routing it’s final destination. Nevertheless, a SOA platform is intended to integrate not only internal composites but...
