连接ActiveMQ的JMX问题

代码如下，连接到128.128.17.1的ActiveMQ服务器，可以确定的是其它机器可以连接到这个ActiveMQ服务器，但是在特定的机器连接时，抛出了异常。
public static void main(String args[]) throws UnknownHostException, IOException
    {
        JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://128.128.17.1:2011/jmxrmi");
        String username = "guest";

        String password = "guest";

        Map env = new HashMap();
        String[] credentials = new String[] { username, password };
        env.put(JMXConnector.CREDENTIALS, credentials);
        JMXConnector connector = JMXConnectorFactory.connect(url, env);
        connector.connect();
        connector.close();
    }
异常如下：

明明连接的ActiveMQ服务器IP是128.128.17.1，但是异常中却提示连接127.0.0.1被拒绝，真是让我抓狂。而且debug到jdk中的jmx代码时，发现看不到debug下的变量值，提示：cannot be resolved to a variable. --------------------编程问答-------------------- http://topic.csdn.net/u/20120708/22/2e29edf2-2473-416f-8e82-cc9dfdfb324c_2.html
