Did you change any of the files in the jms directory? Specifically, did you change hsqldb-jdbc2-service.xml (or perhaps replace it with another file)? That file directs MQ to use DefaultDS as its data source. You mentioned MySQL. Also, the error message "Access denied for user 'jbossuser'@'localhost' (using password: YES))" is a typical MySQL error message. I am assuming that you must have changed hsqldb-jdbc2-service.xml to use a different data source, or replace DefaultDS with MySQL. Until you get the database access issue solved, you will not be able to use the messaging service., and no queue or destinations will show up.
