访问 JBoss 5.1.0.GA 的 mebeans 时出现以下错误。

这是我的java类；

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();
     }
  }

我已经检查了防火墙。它没有问题。如何解决这个问题？

尝试使用 RMI 默认端口：1090。确实，对您的 URL 做一些更改；

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

查看 url 的最后一部分：从“jmxrmi”到“jmxconnector”。
