List vm = new ArrayList();
        jvmList = new JVMListManager();

        vm = jvmList.listActiveVM();

        for (VirtualMachineDescriptor vmD : vm) 
        {
            try
            {

            //importFrom is taking a process ID and returning a service url in a String Format
            String ServiceUrl = ConnectorAddressLink.importFrom(Integer.parseInt(vmD.id().trim()));
            JMXServiceURL jmxServiceUrl = new JMXServiceURL(ServiceUrl);

            jmxConnector = JMXConnectorFactory.connect(jmxServiceUrl, null);
            con = jmxConnector.getMBeanServerConnection();
            CompilationMXBean compMXBean = ManagementFactory.newPlatformMXBeanProxy(con
                   , ManagementFactory.COMPILATION_MXBEAN_NAME
                   , CompilationMXBean.class);
            }catch(Exception e)
            {
            //Do Something  
            }
        }


protected List listActiveVM() {
    List vm = VirtualMachine.list();

    return vm;
}

This requires you to use the jmxremote argument at JVM startup for the process you are trying to read. TO be able to do it without having to pass a jmxremote argument at startup. You will have to use the attach api(only applicable for Programs using Java 6 and higher.
