Now I know! For anyone who is interested: You can overwrite the default use of org.hibernate.secure.JACCPreInsertEventListener and org.hibernate.valitator.event.ValidateEventListener for the pre-insert event and org.hibernate.secure.JACCPreUpdateEventListener, org.hibernate.valitator.event.ValidateEventListener for the pre-update event by adding those lines to the persistence.xml: | <property name="hibernate.ejb.event.pre-insert" value="org.hibernate.secure.JACCPreInsertEventListener"/> | <property name="hibernate.ejb.event.pre-update" value="org.hibernate.secure.JACCPreUpdateEventListener"/> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024995#...
