Hello!I would like to send a request and get a reply from a message handlers onMessage(...) method. Something like this: void MyClass::onMessage(cms::Message m) { cms::Destination* tempDest = session_->createTemporaryQueue(); cms::MessageConsumer* responseConsumer = session_->createConsumer(tempDest); SomeOtherMessageHandler replyHandler; responseConsumer->setMessageListener(&replyHandler); cms::Message* request = session_->createTextMessage(); m->setCMSReplyTo(tempDest); p->send(m); ...wait for response... cms::Message* response = replyHandler.getResponse(); } ...but my code hangs in setMessageListener(...); My guess is that because I am in the onMessage method i have locked a mutex that is required to do setMessageHandler(...) Is this an error or not? In any case, what is the work-around to be able to do request/reply from a message handler?
Do a blocking receive call instead and wait for the response that way.
Thanks in advance. Regards Klaus -- View this message in context: http://activemq.2283324.n4.nabble.com/CMS-3-9-2-process-hangs-when-calling-setMessageListener-in-onMessage-tp4727730.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
