It's just that JBoss 5 is not shipped with some pre-configured jboss messaging destinations. The file is not incomplete. If you want to configure a destination, please read the user's guide that comes with JBM 1.4.1.GA (the version that work with JBoss 5)
An example file showing some example destinations can be found at docs/examples/jms/example-destinations-service.xml.
Thanks Peter that really helped. Thanks a lot for your response.
