If i have JPA code inside an EJB jar, will that be deployed as a bean? As i understand, JPAs work in J2SE environments too? Other than EJB, is there any JPA implementation from Sun?

PS: Am confused between EJB3/JPA/Hibernate. Please clarify.

Yes, there seem to be some confusion here

First, JPA is not beans. JPA is a specification about data persistence. There are no beans, but what is called "Entities". Entites are accessed via an entity manager. It can be used on a EJB3 container or even in J2SE. Again, JPA is a specification. It is implemented by a few JPA containers, like Hibernate or Toplink.
