Is it possible to use the JBoss implementation of EJB3, except with a non-Hibernate persistence provider? In other words, can I replace the underlying Peristence provider with a library of my own? I'm experimenting with a library that has an implementation of EntityManager/EntityManagerFactory (it implements a subset of JPA) that will interface with Amazon's SimpleDB, and it'd be cool to be able to inject the entity manager.
