Hibernate SessionFactory vs. JPA EntityManagerFactory

Question

I am new to Hibernate and I\'m not sure whether to use a Hibernate SessionFactory or a JPA EntityManagerFactory to create a Hibernate Session

Answer 1

By using EntityManager, code is no longer tightly coupled with hibernate. But for this, in usage we should use :

javax.persistence.EntityManager

instead of

org.hibernate.ejb.HibernateEntityManager

Similarly, for EntityManagerFactory, use javax interface. That way, the code is loosely coupled. If there is a better JPA 2 implementation than hibernate, switching would be easy. In extreme case, we could type cast to HibernateEntityManager.
