Now I'm starting to suspect something funny going on with your config. I
received a TransactionNotActiveException when I tried to run your code
without starting the txn, and the fact that you didn't receive that
exception doesn't make any sense to me. I can't explain why you see the
exception and I don't. The best thing would be for you to put together a
stripped down test case that demonstrates the problem. An actual unit test
would be ideal, but if you're not a position to write one then just a simple
standalone servlet should suffice.
Thanks,
Max
