Hibernate was new to me, and I will try to explain just a little bit in this post. I have some very good developers in my team that do the hard work on the hibernate part of this project. I will keep it simple and just explain some of the basics. The persistence layer contains a set of classes and components, which handle the tasks of persisting or retrieving objects to or from the underlying database.

In this case however, instead of forbidding the use of any part of the ADF, my customer decided to allow a Poc (Proof of Concept) in which I (and my co-workers) were allowed to use the ADF-faces part of the framework. The consequence was that we had to think of an alternative appli...
