This is a short post in which I describe what is the behavior of background threads in MAF in regards to the context of the features.

This blog post evaluates the runtime evaluation of the Oracle JCA Adapter endpoint property jca.retry.count on an outbound connection under Oracle SOA Suite 12c compared to Oracle SOA Suite 11g. Obviously, the runtime engine counts differently under 12c compared to 11g. When migrating a project from 11g to 12c, I first noticed this behavior in

The new af:deck component is a very good looking new ADF Faces feature with a lot of possible transitions. It is possible to replace a (simple) task flow with this component, as you will see in this blog entry: If you embed this simple Taskflow in a region on a page, you can switch the
