Thanks to everybody for your valuable adviced.

I ended with an @ApplicationScoped EntityManagerProducer, producing @ViewAccessScoped ExtendedEntityManager.
ExtendedEntityManager is identical to DS JPA example.

So, something very close from DS JPA page example.

http://deltaspike.apache.org/documentation/jpa.html#_extended_persistence_contexts

In fact, I am still a bit puzzled by DS JPA example, because the EntityManager it produces is @RequestScoped.

So, when I basically copied/pasted it, the EM was just opened and closed on every request. And, for an example, session was closed when some hibernate proxies were accessed during serialization...

Do I miss something obvious, or should the doc rather mention that one should use a scope such as @ViewScoped, @SessionScoped or @ViewAccessScoped rather than @RequestScoped ?

Ludovic
