MQSeries (and I suspect most messaging oriented middleware) only provides asynchronous messaging. If you want synchronous, you can achieve *something* similiar using request/reply messages. Send a message and wait for a response message to arrive.

I am not up to speed on it but I believe that MQeveryplace may support synchronous messaging....

If I understand the problem correctly, the javax.jms.QueueRequestor will serve your purpose. Check the request method in that.

The QueueRequestor creates a temporary queue for each request and waits for the reply. Thus will get synchronous request/reply behavior.
