What version of the ESB are you using? 4.0, 4.2 MR2, 4.2 head?
This problem crops up from time to time. I think Kevin nipped again recently.
And can you give us more details as to what your jboss-esb.xml looks like and what you are trying to do?
There should be an exception output to the log. Do you see one?
The problem was related to a missing Queue name defined in jboss-esb.xml, but not in queue-service.xml.
I am using maven to build .ear and it is working so far with basic samples.
Mike, if you think this should have been covered in the docs more, please create a JIRA task so we can address that.
Yes, there will be a DEBUG message in the log file associated with the WARN on the console.
The DEBUG message should be prefixed with "Courier Exception"
