Hello,
i'm using EclipseLink with Pessimistic Lock:

String queryString = "SELECT sfc FROM mytable sfc WHERE sfc.id=:sfcid";
Query query = em.createQuery( queryString );
query.setHint(QueryHints.PESSIMISTIC_LOCK, PessimisticLock.LockNoWait);
query.setParameter("sfcid", id );
List<MyTable> resList = (List<MyTable>) query.getResultList();

When i try to access a row locked, i have org.eclipse.persistence.exceptions.TransactionException, how i can distinguish Lock cases from the others? Can i use "Instanceof" some class or other methods?

Thanks
Rafa

Please include the exception stack trace you are getting. If the exception is being wrapped, you may need to use the caused by of the exception, or pout your try catch around the query execution.
