[jboss-user] [JBoss Seam] - How do I configure a Hibernate Interceptor in Seam?

[JakeC]

I am trying to implement Hibernate db auditing like http://www.hibernate.org/48.html (but adding field, oldValue, and newValue), and I need to create the Session with my custom Hibernate Interceptor, which is given the User ID in the constructor.

The only place in Seam I see any version of SessionFactory.openSession() being used is in ManagedHibernateSession.initSession(), but I don't really see how to get my Interceptor in there. I could extend ManagedHibernateSession and inject currentUser, but how do I configure Seam to use my extended class? I see the Portal sample app pointing to ManagedHibernateSession in components.xml, but we are using EntityManager, with managed-persistence-context declared in components.xml, not Session.

How do I configure a Hibernate Interceptor in Seam?

Or, is there a better way to do Audit logging in Seam? At first I was looking at using the @EntityListeners annotation, but it would involve lots of Reflection, and there doesn't seem to be a way to get at the previous values of the Entity's properties anyway.

org.hibernate.Interceptor.onFlushDirty() gives me all that (too bad it doesn't also give me boolean isDirty[]), but I don't see how to get it configured within Seam.
