Question

Host : serverhost.example.com / 127.0.0.1
Port : 8082
API/Application : Google Chrome / Tomcat deployed application
Monitor : CPU = 35%
          Memory = 30%

这是我的代码段：

String url = "service:jmx:rmi:///jndi/rmi://127.0.0.1:8082/jmxrmi";
JMXConnector jmxc = null;
try {
    JMXServiceURL jmxSvcUrl = new JMXServiceURL(url);
    System.out.println("~~~~~~~~~~~1~~~~~~~~~~~~~~");
    jmxc = JMXConnectorFactory.connect(jmxSvcUrl, null);
    System.out.println("~~~~~~~~~~~2~~~~~~~~~~~~~~");
    MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
    String domains[] = mbsc.getDomains();
    Arrays.sort(domains);
    for (String domain : domains) {
        System.out.println( domain );
    }
    System.out.println("~~~~~~~~~~~3~~~~~~~~~~~~~~");

}catch(Exception ex){
    ex.printStackTrace();
}finally {
    if( jmxc != null )
        try{jmxc.close();}catch(Exception ex){;}
}

我收到了这个错误
