Re-queuing messages when a transaction rolled back

I'm consuming messages asynchronously with a SimpleMessageListenerContainer. That messages calls methods on my service layer, and I intentionally throw an exception in order to test the rollback of the transcaction. I want that the message would be send back to the end of the queue. However it doesn't happen. Someone can help me?

Thanks.

What are the SMLC acknowledgemode and transactional properties set to?

I am out of the country so replies might be sporadic.
