Hi all, I can't understand why I'm getting: java.lang.ClassNotFoundException: org.jboss.mq.server.jmx.Queue On a Linux environment I have set up, but not a Windows one I'm developing on. The jbossmx.jar does not appear more than once on the classpath, and is in it's default directories of: /usr/local/jboss-portal-2.7.0.GA/server/all/lib/ /usr/local/jboss-portal-2.7.0.GA/server/default/lib/ Thanks, Dean.
