OK.. thanks for the reply. This way, Users will the orphan and I need the special Hibernate annotation for orphans to be removed, right? Is there a way of making JBoss really remove User entities itself without that Hibernate-specific annotation? I can't understand what is then the pourpose of the CascadeType.REMOVE (or ALL in this case) as I must "unlink" users from portals setting Portal value to null before removing the portal. Does cascading do any work then? Thanks a lot, Ignacio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4073093#...
