[Jboss-dev-forums] [Design of JMX on JBoss (JBoss/JMX)] - Re: Using the platform MBeanServer in jdk5 environments

[iwadasn <nu...@jb...>]

Was this ever put in? Does it exist in 4.0.2?

If so, how do you turn this on. I would like to see the standard java JMX beans in the jmx-console.

This is the design forums. If you want to ask for help, use the user forums!!!!
If you want to know what is in a release, use the release notes.

The JBoss forums are not a mechanism whereby you can get every frivilous
question answered without doing some research for yourself.

Following up on http://jira.jboss.com/jira/browse/JBAS-1610

The issue is that to start the agent for jconsole "-Dcom.sun.management.jmxremote"
we must have JBossJMX in the CLASSPATH rather than having ServerImpl
setup the system properties and classloader.

We cannot use Sun's MBeanServer because
1) We cannot plugin our UnifiedLoaderRepository
2) It does not do MBean context classloading
3) It is slow for Standard/ModelMBean (see the performance tests in the jmx module)
In fact when we did use Sun's MBeanServer in 2.4.x we had to implement performance
critical mbeans like the EJBContainer using DynamicMBeans. 

Other alternatives:
1) Write a listener for MBeanRegistration events that creates proxies from
the platform mbean server to the JBoss MBeanServer (a poor man's cascading MBeanServer)
2) Deploy a jmx remote connector in JBoss's MBeanServer and use the remote tab
to connect to it from jconsole (including adding the platform XMBeans to JBoss's MBeanServer).

Or Scott's alternative LazyMBeanServer.
http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMBeansInJConsole
that delegates to JBoss's MBeanServer (when it is available) for non platform XMBeans.

I think a new jmx remote connector is what we really need, because even with the current workaround, there are still the problems of accessing objects that are not really designed for remote access.

We need a flexible connector that can be configured for remote class loading and even custom serialization/object replacement of non-remotable objects. I would have looked at this first but I was not sure how far Tom has gotten with the current implementation.

We might be able to do something with the extension points

http://java.sun.com/j2se/1.5.0/docs/api/javax/management/remote/JMXConnectorServer.html#setMBeanServerForwarder(javax.management.remote.MBeanServerForwarder)

or jmx.remote.protocol.provider.class.loader
http://java.sun.com/j2se/1.5.0/docs/api/javax/management/remote/JMXConnectorServerFactory.html

I'm not that familiar with JSR160

Another workaround I was using, is to explicitly set the jboss classpath and the mbeanserver builder in a batch file (like what Main and ServerLoader would do), so only one mbeanserver gets created (the platform one).

I've added that as a subtask to the case:
