In the examples I’ve seen, JPA doesn’t fundamentally change design patterns for Java EE, it’s a standard implementation of persistence. You can (should, depending on your constraints?) still hide the persistence implementation behind a DAO layer – maybe the transition is a good test of whether your existing DAOs are doing a good job of hiding those implementation details.
There’s an tutorial that does that on developerworks. There’s also a discussion about whether JPA killed the DAOs on infoq that you might find of interest.
