JMX实现监控weblogic问题

工作须要，得监控weblogic的指标，例如:连接池、线程数、JMS明细、EJB明细,等指标!在网上了解了一下JMX原理，也做了一个JMX的Hello例子，但是要监控weblogic不知道如何动手，得到了与weblogic的Mbeanserverconnection,但是不知道怎么得到我要的监控指标，是还要注册相应的Mbean？该Mbean要怎么写呀？又怎么从Mbean上得到相应的监控数据,自己做的JMX例子好像太浅，希望哪位JMX老手指点一下，能否提供点JMX资料!我得到Mbeanserverconnection的代码如下:
private static MBeanServerConnection lookupMBeanServer9(String ip, String port, String name, String pass)
    {
        String protocol;
        String s5;
        protocol = "t3";
        s5 = "/jndi/weblogic.management.mbeanservers.runtime";
        MBeanServerConnection mbeanserverconnection;
        try
        {
        //JarLoader jarloader = new JarLoader((new StringBuilder()).append(".").append(File.separator).append("working").append(File.separator).append("classes").append(File.separator).append("weblogicclient9.jar").toString());
        //Thread.currentThread().setContextClassLoader(jarloader);
        JMXServiceURL jmxserviceurl = new JMXServiceURL(protocol,ip, Integer.parseInt(port), s5);
        Hashtable hashtable = new Hashtable();
        hashtable.put("java.naming.security.principal", name);
        hashtable.put("java.naming.security.credentials", pass);
        hashtable.put("jmx.remote.protocol.provider.pkgs", "weblogic.management.remote");
        JMXConnector jmxconnector = JMXConnectorFactory.connect(jmxserviceurl, hashtable);
        mbeanserverconnection = jmxconnector.getMBeanServerConnection();

        return mbeanserverconnection;
        }catch(Exception ex){
        ex.printStackTrace();
        }
        return null;
    }
