基本に戻って HelloWorldExample

やはり、そのままでは動かない...

Java 5.0 では Server を取得し、MBean を登録するだけで、後は適切な
com.sun.management.jmxremote プロパティを指定すればそれで JConsole
からみえるようになるが、MX4J ではそうはならない。コネクタ周りの造りが
違うということだ。

mx4j.examples.remote.simple.Server から名前登録らしき部分を
借用。しかし、このままでは bind のエラーが出る。おそらく JBoss が
同じように 1099 に rmiregistry サービスを起動しているため。
JBoss をとめると最終的には動作した。

動作するまでに、いくつか ClassNotFoundException を解決する
必要があった。mx4j.jar はすべてを含んでいるわけではなく、
mx4j-remote.jar, mx4j-tools.jar もクラスパスに含める必要が
あった。

     // Create an instance of MBeanServer
     MBeanServer server = MBeanServerFactory.createMBeanServer();

     // Create an ObjectName for the MBean
     ObjectName name = new ObjectName(":mbean=helloworld");

     // Create and register the MBean in the MBeanServer
     server.createMBean("mx4j.examples.mbeans.helloworld.HelloWorld", name, null);

     // Invoke a method on it
     server.invoke(name, "reloadConfiguration", new Object[0], new String[0]);

 ///////////////////// Begin Additional Code
     ObjectName namingName = ObjectName.getInstance("naming:type=rmiregistry");
     server.createMBean("mx4j.tools.naming.NamingService", namingName, null);
     server.invoke(namingName, "start", null, null);
     
     int namingPort = ((Integer)server.getAttribute(namingName, "Port")).intValue();
     // int namingPort = 1099;
     String jndiPath = "/jmxconnector";
     JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://localhost/jndi/rmi://localhost:" + namingPort + jndiPath);
      
     // Create and start the RMIConnectorServer
     JMXConnectorServer connectorServer = JMXConnectorServerFactory.newJMXConnectorServer(url, null, server);
     connectorServer.start();
     
     System.out.println("namingPort="+namingPort);
 ///////////////////// End Additionall Code

     // Invoke an attribute on it
     Integer times = (Integer)server.getAttribute(name, "HowManyTimes");

     System.out.println("The configuration was reloaded " + times + " times.");

     try { Thread.sleep(1000*1000); } catch (Exception e) {}
