I've tried:

and that results in a HibernateException /hibernate.cfg.xml not found.
Well, since the system is using a persistence.xml, that makes sense.

So, how am I supposed to get a Session Factory?

I take it you're using JPA then? http://docs.jboss.org/hibernate/core/4. ... tstrapping

Reading through that stuff again...
Okay, I'm guessing you mean I should set the hibernate.ejb.session_factory_observer property?
Hmm, that does look like it will do what I need. Hope it works.
Thanks.

Actually I was referring to the top of the section (manager1 below is replaced with the name of your persistence unit in persistence.xml):


If you really need access to the SessionFactory or Session after that you can use:


But if you're using JPA, you should be using EntityManager and EntityManagerFactory.
