I'm facing the same problem but with another idea in my mind: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=118991 I have been dealing with a similar problem in a previous project at work where we used Hibernate. The solution was to create a backing session that will help you recover gracefully in case of DBException/ContraintViolation. I was wondering if something similar can/should be done in Seam/EJB3.
