Thanks for the input. I have never heard that you must use the proxy in this scenario. I have seen this statement (from JBoss trailbalzer):
"In EJB 3.0 applications, transaction properties are most frequently declared for methods in session beans. If a method requires transaction, all operations in the method, including database updates, are only committed after the method exits normally."
If it is true that a proxy based call is required then it would be very important to include that in or near the above paragraph. Where is this documented? I would like to read up on this. I expect that reading has other useful info.
I made a change to use the proxy call and I still get the same exact result!
In other words I now, in a non SLSB class, lookup the interface and make a call in a loop. The called method has @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) .
FYI: If I call it passing a series of valid SQL all statements execute okay. I have some scenarios where some sql statements in a list will error (long story). I need to ignore those and continue.
I am guessing there is something else I need to do (like .. reset the em, whatever that means ) when the error occurs but I am not sure what. The fact that the same em is used between calls is probably the root cause.
