The EntityManager has a getDelegate API: http://java.sun.com/javaee/5/docs/api/javax/persistence/EntityManager.htm... You can probably do this: | @PersistenceContext | EntityManager em; | | public void myMethod() { | | //get the underlying Hibernate session | org.hibernate.Session sess = (org.hibernate.Session) em.getDelegate(); | | //now get the session factory from the hibernate session | SessionFactory sf = sess.getSessionFactory(); | } P.S: I don't know why JPA doesn't provide a similar getDelegate() method on the EntityManagerFactory to access the provider specific entitymanagerfactory.
