EntryDuplicatedException is a custome exception I have:


  | 
  | @ApplicationException(rollback = true)
  | public class EntryDuplicatedException extends Exception {
  | 
  |     public EntryDuplicatedException() {
  |     }
  |    
  | }
  | 

addDuplicatedMessage() is just a simple method to add the error message to the view (FacesMessages..)

Finally, you should use @TransactionAttribute(REQUIRES_NEW) for the especific method you want to recover after the transaction fails:


  | @TransactionAttribute(REQUIRES_NEW)
  |     public void update(User entity) throws ConcurrencyException, EntryDuplicatedException {
  |         try {
  |             em.merge(entity);
  |             em.flush();
  |         } catch (EntityExistsException ee) {
  |             throw new EntryDuplicatedException(ee);
  |         }
  |     }
  |
