I am using hibernate validation for JPA entities and ejb3 stateless session beans. When the entity has a generated value id, the InvalidStateException is itself thrown to the ejb client (a servlet in my case). However, when the entity's id isn't annotated with @GeneratedValue, the InvalidStateException is thrown in a PersistenceException which is in a JBossRollbackException which is in a RuntimeException. Does anyone know the reason for that or if there is anything I can do to make it always throw the InvalidStateException directly and not wrap it in 2 other exceptions? (I'm using MySQL) Thanks.
