訪問JBoss 5.1.0.GA的mebeans時出現以下錯誤。如何在訪問JBoss 5.1.0.GA的mbeans時解決「javax.management.InstanceNotFoundException」？

這是我的java類;

public class JBossJMXClient { 
    public static void main(String[] args) throws Exception { 
     String host = "192.168.0.249";// Your JBoss Bind Address default is 
            // localhost 
    int port = 4545; // management-native port 
     String urlString = "service:jmx:rmi:///jndi/rmi://" + host + ":" + port 
      + "/jmxrmi"; 
     System.out.println("  \n\n\t**** urlString: " + urlString); 
    JMXServiceURL serviceURL = new JMXServiceURL(urlString); 
    JMXConnector jmxConnector = JMXConnectorFactory.connect(serviceURL, 
      null); 
    MBeanServerConnection connection = jmxConnector 
      .getMBeanServerConnection(); 

    // Invoke on the JBoss AS MBean server 
    int count = connection.getMBeanCount(); 
    System.out.println(count); 
    ObjectName objectName = new ObjectName("jboss.system:type=ServerInfo"); 
    String javaVersion = (String)connection.getAttribute(objectName, "JavaVersion"); 
    System.out.println(javaVersion); 
    jmxConnector.close(); 
    } 
    }

我已經ckecked firewall.It沒有problem.How來解決這個問題？

嘗試使用RMI默認端口：1090.的確，在URL中做一些更改;

String urlString = "service:jmx:rmi:///jndi/rmi://" + host + ":" + port + "/jmxconnector";

查看url的最後部分：從「jmxrmi」到「jmxconnector」。
