Access Geronimos JMX System with JConsole

[Thomas Darimont]

Hello,

I'm was able to access the JMX Subsystem of Websphere Application Server 
Community Edition 1.0.1.1(which ist build on top of geronimo) using the 
following code:

package de.tutorials;

import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;

import javax.management.MBeanServerConnection;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;

/**
 * @author Tom
 */
public class JMXWebsphereInspector {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        Map env = new HashMap();
        String[] credentials = new String[] { "system", "manager" }; 
//default
        env.put("jmx.remote.credentials", credentials);

        MBeanServerConnection connection = JMXConnectorFactory
                .connect(
                        new JMXServiceURL(

"service:jmx:rmi:///jndi/rmi://localhost:1099/JMXConnector"),
                        env)
                .getMBeanServerConnection();

        System.out.println(Arrays.toString(connection.getDomains()));
    }
}

However, if I try to access the JMX Subsystem using JConsole I can 
connect but I don't see any MBeans.

The client runs on Sun JDK 1.5.0_05 and the Server runs on IBMs
JDK 1.4.2

My settings
URL: service:jmx:rmi:///jndi/rmi://localhost:1099/JMXConnector
Username: system
password: manager

On the console I can see the following Error Message:

 C:\Documents and Settings\Tom>jconsole
Error when synchronizing with MBeanServer : 
javax.management.InstanceNotFoundException: 
JMImplementation:type=MBeanServerDelegate

I looked at the mx4j and learned that the mx4j.server.MX4JMBeanServer 
registers itself using
new ObjectName("JMImplementation", "type", "MBeanServerDelegate"); in 
the Ctor. So the instance should be there...

Any hints?

Kind regards,
Thomas
