Glassfish should automatically enhance your entities if you use a container managed EntityManagerFactory. The container is required to use the createContainerEntityManagerFactory method, this is where OpenJPA provides a ClassTransformer (actually the same agent that you mentioned before).
So if you're using @PersistenceContext or @PersistenceUnit you should get enhancement for free in a JEE environment. If you create the EntityManagerFactory yourself through javax.persistence.Persistence then you'll have to do your own enhancement. Of course doing the enhancement yourself like Rick mentioned never hurts. I have no real experience with Glassfish either, there might be something you need to do to install a third party provider (non EclipseLink / Toplink). It might be worth posting on the Glassfish email lists and see if anyone else has had similar experiences. Hope this helps, -mike On Tue, Aug 18, 2009 at 2:01 PM, Rick Curtis <curti...@gmail.com> wrote: > > Another option would be to enhance your classes at build time.
