Max Rydahl Andersen commented on EJB-325:
-----------------------------------------

btw. being able to get the persistenceunit name from an EntityManager or EntityManagerFactory would be awsome too...I couldn't find a way and our delegates are just hibernate interfaces which does not know about it....and the logs reveals nothing.
