What Linux distro? I do not recognize the command you mentioned: "/jboss stop" The typical mechanism to stop the app server (assuming it is running on the same box and is using the default JNDI port)is: ./shutdown.sh -S Also do this. Open the jmx-console, go to the jboss:service=JNDIView mbean and invoke the "list" operation and post the results. It would appear that either JNDI is messed up, or perhaps JNDI is not using the default port (1099). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166209#...
