My JMS Receiver or MDB cannot see a message sent in the same transaction?

Question

I sent a message to a destination. My JMS client does not receive it. The receive always times out, or blocks infinitely if i use the no-timeout call

Answer

You are trying to the send/receive in the same transaction.

In a transaction, the send won't occur until the transaction commits...which it nevers does.

Because you are waiting in receive() for a response on a message that was never sent.
