1. Re: JConsole doesn't work anymore
jaikiran Nov 5, 2008 2:09 AM (in response to dmlloyd)In earlier versions of JBoss (ex: 4.2.3 GA), the run.jar file in %JBOSS_HOME%/bin contained this org.jboss.system.server.jmx.* package/classes. However in the current version (JBoss-5 CR2), i don't see any such org.jboss.system.server.jmx.* classes in that run.jar. So at the first step of booting, the server throws:

Not sure if these classes were intentionally moved out of the run.jar.
P.S: The %JBOSS_HOME%/lib/jboss-system-jmx.jar does contain these classes but the exception occurs too early for this jar to come into picture. -
2. Re: JConsole doesn't work anymore
dmlloyd Nov 5, 2008 12:50 PM (in response to dmlloyd)Inicidentally I tried adding various jars to the boot classpath just to see if I could make it work - after about three I gave up though. It's a shame that this doesn't work...

3. Re: JConsole doesn't work anymore
jaikiran Nov 6, 2008 1:58 AM (in response to dmlloyd)I tried a couple of things. And i think the subject of this thread might need a change :)
JConsole does work in JBoss-5 CR2. I followed these steps here http://www.jboss.org/community/docs/DOC-12499
However, displaying of JBoss MBeans in JConsole as explained here http://www.jboss.org/community/docs/DOC-10521, no longer works because of the classpath issue.
I tried bringing the jboss-system-jmx.jar into the boot classpath (just for testing). That got me to a point where i could see JBoss booting but it failed with various other classloader/dependency errors. Let me try a few more things and see if there is a workaround. In any case, should this be reported in the JIRA (or has it been already done)? -
4. Re: JConsole doesn't work anymore
jaikiran Nov 6, 2008 10:50 AM (in response to dmlloyd)The only way, i could get the JBoss MBeans in JConsole working was to manually add the following 2 classes to the %JBOSS_HOME%/bin/run.jar:
org\jboss\system\server\jmx\LazyMBeanServer.class
org\jboss\system\server\jmx\MBeanServerBuilderImpl.class -

I could not find a related issue, so created one https://jira.jboss.org/jira/browse/JBAS-6185 -
6. Re: JConsole doesn't work anymore
dmlloyd Nov 9, 2008 11:29 AM (in response to dmlloyd)I tried another approach - namely, specifying that the platform MBean server be used (which would avoid the classpath issue), but the failure is different:
10:27:26,880 ERROR [AbstractKernelController] Error installing to Instantiated: name=jboss.system:service=MainDeployer state=Described mode=Manual requiredState=Configured org.jboss.deployment.DeploymentException: Unable to createMBean for jboss.system:service=MainDeployer ... Caused by: javax.management.InstanceNotFoundException: JMImplementation:type=MBeanRegistry at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getMBean(DefaultMBeanServerInterceptor.java:1094) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:833) at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:761) at org.jboss.system.ServiceCreator.installPlainMBean(ServiceCreator.java:203) at org.jboss.system.ServiceCreator.install(ServiceCreator.java:115)
The exact properties I set were:-Dcom.sun.management.jmxremote -Djboss.platform.mbeanserver=true
Perhaps there's something somewhere that isn't respecting this setting... -

dmlloyd Nov 9, 2008 11:50 AM (in response to dmlloyd)...which is of course exactly what http://www.jboss.org/community/docs/DOC-10521 is about, so... ignore me...

Funny, I didn't see this forum posting, so of course I went through my own attempt iteration in this comment:
http://www.jboss.org/community/docs/DOC-10521#comment-1390
Glad to see I'm not the only one who has hit this. :)
