Examples of javax.persistence.NoResultException

javax.persistence.NoResultException
Thrown by the persistence provider when getSingleResult() is executed on a query and there is no result to return. This exception will not cause the current transaction, if one is active, to be marked for roll back. @author Emmanuel Bernard
