[eclipselink-users] Database exceptions & enhanced Entities/Controllers
|
Hi
I've got the following code in my enhanced DAO class (EclipseLink with
Spring as the DI container)
@Transactional
public void create(Users users) throws PreexistingEntityException,
Exception {
try {
em.persist(users);
} catch (Exception ex) {
System.out.println("Trying to create new user but user " +
findUsers(users.getUsername() + " already exists"));
if (findUsers(users.getUsername()) != null) {
throw new PreexistingEntityException("Users " + users + "
already exists.", ex);
}
throw ex;
} finally {
if (em != null) {
em.close();
}
}
}
However, when I deliberately try to add a duplicate entry the exception is
not being caught and the System.out output is not appearing although
extensive exception output is displayed (appended below). I can't add
breakpoints to my DAO class as Eclipse won't allow this because the class is
enhanced.
Is this a consequence of enhancement, in which case how do I detect an
attempt to add a duplicate entry - or am I missing something obvious?
Regards
