Take jconsole.jar out of the -J classpath. It's already set in the jconsole launcher.
===== Update =====
Hmmm.... I take back my suggestion. I have a windows batch file I use [which works] which adds a JAR to the classpath. The intent is to add the JMXMP JMX client into jconsole and then launch to the argument specified JMX Service URL. It looks like this:
@echo off
start /B jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;MY-JAR-PATH\jmx-optional-1.0-b02-SNAPSHOT.jar service:jmx:jmxmp://localhost:%1
If a command like that does not work (i.e. jconsole still will not launch, but does not error out either), then you need to figure out where it is stalling. 2 suggestions for this:
- Launch another jconsole and attach to the stalled jconsole by PID, switch to the Threads tab and eyeball what's going on in the main thread.
- Or, (since it looks like you're in windows) hit Ctrl-Break and hopefully it will print out a thread dump to the console and you can then eyeball the main thread going-ons there.
Post back if you get anything (or if you don't....)
