Getting an MBean implementation to self register

Question

Have a number for Jetty server/servlet combos each running in their own JVM that I want to register with a MBeanServer running in still another JVM. So I took client code to do this. The server class looks lik this:
package com.sra.pipeline.servers.htmlexport;
import java.io.IOException;
import java.net.MalformedURLException;
import javax.management.InstanceAlreadyExistsException;
import javax.management.MBeanException;
import javax.management.MBeanRegistrationException;
import javax.management.MBeanServerConnection;
import javax.management.MalformedObjectNameException;
import javax.management.NotCompliantMBeanException;
import javax.management.ObjectName;
import javax.management.ReflectionException;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;
import org.jingle.jmxremote.client.MBeanServerImpl;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.servlet.Context;
import org.mortbay.jetty.servlet.ServletHolder;
public class HtmlExportServer implements HtmlExportServerMBean {
     private static int port;
     private static Server server;
     private static String name = "HtmlExportServer";
     private static HtmlServlet servlet;
     public static void main(String[] args)
          throws Exception {
         registerBean();
         if(args.length == 1) {
             port = Integer.parseInt(args[0]);
         }else {
             port = 8090;
                    Server server = new Server(port);
                    Context context = new Context(server,"/",Context.SESSIONS);
                    servlet = new HtmlServlet();
                    context.addServlet(new ServletHolder(servlet), "/*");
                    server.start();
                    server.join();
     public String getName() {
         return name;
     public boolean haveConnection() {
         return (servlet.hasConnection());
     public boolean isRunning() {
         return (server != null);
     public static void registerBean() {
                    try {
             JMXServiceURL url = new JMXServiceURL(
                 "service:jmx:rmi:///jndi/rmi://localhost:9999/server");
             JMXConnector cs = JMXConnectorFactory.connect(url, null);            
             MBeanServerConnection mbsc = cs.getMBeanServerConnection();           
             ObjectName mbeanName = new ObjectName("com.sra.pipeline.servers:type=HtmlExportServer");
             mbsc.createMBean("com.sra.pipeline.servers.HtmlExportServer",mbeanName);
             //MBeanServerImpl mbsi = new MBeanServerImpl(mbsc);
             //mbsi.registerMBean(new HtmlExportServer() , mbeanName);
         } catch (MalformedURLException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         } catch (MalformedObjectNameException e) {
             e.printStackTrace();
         } catch (NullPointerException e) {
             e.printStackTrace();
         } catch (InstanceAlreadyExistsException e) {
             e.printStackTrace();
         } catch (MBeanRegistrationException e) {
             e.printStackTrace();
         } catch (NotCompliantMBeanException e) {
             e.printStackTrace();
         } catch (ReflectionException e) {
             e.printStackTrace();
         } catch (MBeanException e) {
             e.printStackTrace();
}When I used the createBean method of the MBeanServerConnection in the code above, I got
javax.management.ReflectionException: The MBean class could not be loaded by the
default loader repository
this despite the fact that the MBean Interface and the implementing class are both in the classpath of the MBeanServer.
When I used MBeanServerImpl.registerBean I get
Exception in thread "main" javax.management.JMRuntimeException: javax.management
.remote.JMXServerErrorException: java.lang.NoClassDefFoundError: org/jingle/util
/dydelegation/DelegationInvocationHandler
This class from jmxremote is also in the classpath.
So what gives?

I think I am having classpath problems with this in general. I'm running this on windows with the following bat file
set cPath=bin;lib/jetty-6.1.9.jar;lib/jetty-util-6.1.9.jar;lib/servlet-api-2.5-6.1.9.jar;lib/tools.jar;lib/tsapi.jar;lib/bcel-5.1.jar;lib/dunamis.jar;lib/jmxremote-all.jar
java -cp %cPath%  com.sra.pipeline.servers.htmlexport.HtmlExport
set cPath=My current error is no class definition found for javax.servlet.Servlet
This file exists in jetty-6.1.9.jar
Is this a problem with a polluted path, or what
Any ideas would be appreciated.
