guys
in my JPA code a NoResultException causes the transaction to be rollback.
i am using the spring txn manger but all JPA methods are @Transactional(
propagation=Propagation.NOT_SUPPORTED).
any help pls.
@Transactional( propagation=Propagation.NOT_SUPPORTED)
public void txnMethod( Collection<Long> list) throws
ApplicationExecption{
for (Iterator<Long> iterator = list.iterator(); iterator.hasNext();)
{
Long fbId = iterator.next();
PositionUser user = null;
final Query query =
em.createNamedQuery(PositionUser.FIND_BY_FB_ID);
query.setParameter("facebookId", fbId);
try {
user = (PositionUser) query.getSingleResult();
}
catch (NoResultException e) {
log.info( "error occured:" + e.toString() );
}catch (NonUniqueResultException e) {
throw new ApplicationExecption(e);
}
if(user!= null) {
List<Key> friends = user.getFriends();
PositionUser findUser = em.find(PositionUser.class,
friends.get(0));
findUser.getFriends().remove(user.getKey());
em.merge(findUser);
}
em.remove(user);
}
}
-lp
