Hibernate StatisticsService MBean doesnt work with EntityMan

[adlepoo]

Does anybody know how to get a SessionFactory from an EntityManagerFactory under JBoss? The EntityManagerFactory from JNDI is not an instance of HibernateEntityManagerFactory so I can't use it for the StatisticsService.setSessionFactory() method.

The EntityManager has a getDelegate API: http://java.sun.com/javaee/5/docs/api/javax/persistence/EntityManager.html#getDelegate()

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.

Thanks! I like your solution better than the one I was testing.
I set the hibernate.session_factory_name property and did a JNDI lookup to get the SessionFactory.

It seems to work, but I like getting the SessionFactory directly from the EntityManager (via EMFactory) instead of a backdoor method.
