What is the best way to handle a ConstraintViolationException with EJB3 and entitymanager in an SLSB

Programmer Question

here is my code snippet:

@Stateless
public class mySLSB {

@PersistenceContext(unitName = "db")
private EntityManager myEntityManager;

 public void crud(MyEntity myEntity) throws MyException {
  myEntityManager.merge(myEntity);
 }
}

However this merge can cause a ConstraintViolationException, which does not throw MyException (which is caught in the calling servlet).

What is the best way to catch hibernate exceptions ?
