Below is the configuration that my app is using. There's more information there than you need. I had to "clean" it somewhat before posting so hopefully I didn't make any mistakes. I use token replacement {$...} with JVM properties in the jboss.xml so that I don't have to hard code WSMQ configuration when deploying to different environments.
