I have several services configured in jboss-esb.xml, when I send message to one of the service, my message will be received by one of the configured services (even though the message is not meant for that service)!

If I send the same message again, another service will process that message (in round-robin maner), it is not random, it is like each service takes turn to intercept the message.

Example, if I have 3 services configured. First time I send a message, Service 1 will receive it, second time I send a message, Service 2 will receive it, third time I send the message, Service 3 will receive it. Fourth time I send it, Service 1 will receive it and the cycle repeat..

I suspect there is something wrong with the way I configured my jboss-esb.xml, but I am clueless.

Here is how I invoke the service,

ServiceInvoker invoker = new ServiceInvoker("NTIAdaptor", "SearchAccountByParentInternalId");
Message replyMessage = invoker.deliverSync(requestMessage, TIMEOUT);

And here is the jboss-esb.xml,

<?xml version="1.0"?>

You are experiencing that problem because you're using the same jms-bus across services. Try using a different jms-bus for each service jms listener.

  • But if my JMS is configured in such a way that it publishes the messages to all the services listening to it, then would all msgs reach not to all services? Do I need to configure different JMS in such case also? – Vishal Jun 06 '13 at 09:13

If is not what Manuel says, we had a similar problem to yours, messages were getting to the wrong services. In our case it was that the juddi register wasn't altered when we changed a listener from one services to another. So we ended with 2 services listening to the same queue.
