I do use a Action + Service pattern in order to catch all EJB/JPA exceptions and stay in the same page or display a pretty nice error messages. The action is a simple POJO and the Service is an @EJB , @TransactionAttribute(REQUIRES_NEW) over the method makes me happy in this case. IIRC, I've already post in this forum how I'm doing (time ago). HTH. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085551#...
