Hi I’m trying to get a simple C++ P2P request-response example working using a fixed queue known to both the client and server to deliver the request and a temporary queue provided by the client for the server to respond on. I’ve used the OpenWire amq_examples as a basis for the code, running with ActiveMQ 4.0.2, OpenWire 0.1.2 on SLES 9. The client is synchronous, it publishes the request and then blocks (newBlockingMessageConsumer) on receive() awaiting the arrival of the response. The server is also synchronous (eventually to be asynchronous) it blocks on receive() to pickup the request and then publishes the response setting the destination of the outgoing message to that of the temporary queue supplied in the request, using replyTo(). The request-response sequence is repeated with a 1 second delay between each transaction.
Here’s what I get: 1st iteration Client: sends request Server: receives request Server: responds on temporary queue Client: receives response 2nd iteration Client: sends request Server: receives request Server: responds on temporary queue All stops at this point, the client never receives the second response and both processes sit waiting. This is always the case, I’ve tried stopping and restarting the broker and carrying out a re-run but no luck. Note I get the same results if I run the client and server on separate machines with their own broker as when I run both on the same machine with one broker. Now if I use my C++ client to a Java server it works fine, so it looks like my C++ server is dodgy. I’ve used the command line tool “browse” to check out the fixed and temporary queues at the end of the second iteration but find no messages present. At the moment we are running with Non Persistent and Non Durable. Should I be setting the acknowledge mode and if so how do I set it using the BrokerSession I/F? I notice that there a couple of reports in this area (AMQ-843 & AMQ-487) but they do not match exactly what I’m seeing. I’m new to ActiveMQ so suspect its finger trouble on my part, any help would be appreciated, thanks.
