How to gather Hibernate Statistic when using seam managed pe

I'm trying to gather some 2nd-level cache statistics but I don't know how to get a hold of the Hibernate SessionFactory since seam creates and injects the EntityManager to my DAO for me.

Anyone can give me some clues?

I might be wrong but you are probably able to cast the injected entitymanager to org.hibernate.ejb.HibernateEntityManager, and then do
castedEntityManager.getSession().getSessionFactory() / getStatistics()

Session session = (Session) entityManager.getDelegate()

I think it is a better idea to access the statistics via the Hibernate JMX statistics MBean. I don't see an easy way to get access to the SessionFactory programmatically if you are working with JPA. You can't get it from the Session/EntityManager.

Oh I am wrong, you can get the SF from a Session.

Thanks Christian.

There is a method call in Session to get its SessionFactory...i have to look at the api more careful :-) ... I was not expecting a Session to be aware of the factory that creates it....little (pleasant) surprise.
