JBossESB is still running fine except one issue. I want to simply send one message from one service to another.
Therefore I am using the method deliverSync from the ServiceInvoker.
The service is running fine. I am receiving an answer but after some time I see the message
Error processing courier, backing off for 1000 milliseconds
You may need to specify a reply queue in order for the deliverSync method to work properly. This is done by creating a new queue with "_reply" on the end of it's name. The "error processing courier" message is probably happening when the two way courier fails to get the response message from the target ESB.
