I forgot to mention that JBoss doesn't wrap the InvalidStateException in EJBException because I marked this exception as an application exception, and as one that requires rollback in ejb-jar.xml the following way: <application-exception> | <exception-class>org.hibernate.validator.InvalidStateException</exception-class> | <rollback>true</rollback> | </application-exception> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3994269#...
