An additional note: Up to and including installing JBoss Messaging 1.4.2.GA (and making the necessary adjustments), everything works perfectly ... I wrote a program to deploy a queue and a producer to send xml data from an eXist DB to a receiver ... and another program to destroy the queue ... works like a charm. Also, the JMX console (JMX Agent View) is showing in a browser. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213132#...
