Hi Peter, That certainly fixed the issue with the exception - thx. My command is now: D:\JBoss_Tomcat\bin>twiddle -s localhost:1098 get "jboss.web:host=localhost,path=/MyApp,type=Manager" activeSessions But now when I execute that command, nothing happens - the cursor just sits there and the command window never returns to a prompt. Is there a log file or something that would give me a clue as to why the command never seems to complete? Cheers, Paul View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175181#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
