創建RMI連接器客戶端

我正在嘗試連接到MBean服務器。我需要編寫JMX客戶端應用程序。這是用於客戶端應用程序的代碼。但是，我有相關的異常此創建RMI連接器客戶端

無法檢索的RMIServer存根： javax.naming.ServiceUnavailableException [根異常是 java.rmi.ConnectException：拒絕連接主機：本地主機; 嵌套異常是：

有人可以幫我解決這個問題。

import java.io.IOException; 
import javax.management.MBeanServerConnection; 
import javax.management.MBeanServerInvocationHandler; 
import javax.management.MalformedObjectNameException; 
import javax.management.ObjectName; 
import javax.management.remote.JMXConnector; 
import javax.management.remote.JMXConnectorFactory; 
import javax.management.remote.JMXServiceURL; 


public class SystemConfigClient { 

    public static final String HOST = "localhost"; 
    public static final String PORT = "1099"; 


    public static void main(String[] args) throws IOException, MalformedObjectNameException { 
     JMXServiceURL url =new JMXServiceURL("service:jmx:rmi:///jndi/rmi://" + HOST + ":" +PORT+ "/jmxrmi"); 

     JMXConnector jmxConnector = JMXConnectorFactory.connect(url); 
     MBeanServerConnection mbeanServerConnection = jmxConnector.getMBeanServerConnection(); 
     //ObjectName should be same as your MBean name 
     ObjectName mbeanName = new ObjectName("ifs.demo1.jmx:type=SystemConfig"); 

     //Get MBean proxy instance that will be used to make calls to registered MBean 
     SystemConfigMBean mbeanProxy = 
      (SystemConfigMBean) MBeanServerInvocationHandler.newProxyInstance(
       mbeanServerConnection, mbeanName, SystemConfigMBean.class, true); 

     //let's make some calls to mbean through proxy and see the results. 
     System.out.println("Current SystemConfig::" + mbeanProxy.doConfig()); 

     mbeanProxy.setSchemaName("NewSchema"); 
     mbeanProxy.setThreadCount(5); 

     System.out.println("New SystemConfig::" + mbeanProxy.doConfig()); 

     //let's terminate the mbean by making thread count as 0 
     mbeanProxy.setThreadCount(0); 

     //close the connection 
     jmxConnector.close(); 
    } 

}

我曾與下面的參數運行這段代碼。

Dcom.sun.management.jmxremote Dcom.sun.management.jmxremote.port = 1099 Dcom.sun.management.jmxremote.authenticate =假 Dcom.sun.management.jmxremote.ssl =假

，但我得到了

什麼jboss版本？ – Nicholas 2013-05-02 11:45:04

您是否注意到您正在使用具有「D」而非「-D」的VM參數？還是僅僅是一個錯字？正確的是：

-Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=1099 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false
