Hi,
is normal when I call getSingleResult of EntityManager, if query doesn’t return any result, is fired an exception
NoResultException: getSingleResult() did not retrieve any entities.
is not better return null from getSingleResult ?

Hi,
No, it is not better to return null. It is intended to throw NoResultException
.
Use #getFirstResult()
instead if you need null in case of empty result. All details are documented in JavaDoc.
