some dumb questions:

i am using Seam with JPA (with Hibernate implementation) and considering to dump it in favor of plain good old Hibernate. I am basing my decision on the fact that I cannot map interfaces to tables with JPA.

1- am I on the correct track ?

Now the dumbest part: I am not sure if mapping will be still easy, using annotations as in JPA.

2- Is Hibernate annotations meant to be a JPA feature only or there exists extensions to Hibernate annotations to make use of full Hibernate features, those beyond JPA?

For instance, can I map an interface to a table with annotations or do I have to use hbm.xml mapping?
