JBoss MBean NotificationListener問題

我在JBoss上使用NotificationListener有一些問題。JBoss MBean NotificationListener問題

我在JBoss上有一個MBean，我可以連接並調用他們的方法。但是，當我嘗試添加通知Ÿ獲得下一個例外：

我打電話的MBean形成客戶JBOSS

主要的代碼之外是：

 
Properties env = new Properties(); 
      env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); 
      env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); 
      env.put(Context.PROVIDER_URL, "jnp://localhost:1099"); 

      InitialContext ctx; 
      ctx = new InitialContext(env); 

      MBeanServerConnection server = (MBeanServerConnection)ctx.lookup("jmx/invoker/RMIAdaptor"); 


       // get reference to CacheMgmtInterceptor MBean 

       String cache_service = "ar.com.cube3.framework.modulos.msn:jndiName=msnControl,service=MSNControlAcceso"; 
       //String cache_service = "jboss:service=JNDIView"; 
       ObjectName mgmt_name = new ObjectName(cache_service); 
//    
       server.addNotificationListener(mgmt_name,(NotificationListener) new MyListener(), new NotificationFilter() { 


       private static final long serialVersionUID = 6404657810887052083L; 

       public boolean isNotificationEnabled(Notification notification) { 
        // TODO Auto-generated method stub 
        return true; 
       } 
      }, null); 

      Object obj[]= {"test"}; 
      Object temp = server.invoke(mgmt_name, "registrarMsnMessenger", obj, new String[]{String.class.getName()}); 
      System.out.println(temp); 
     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }

和notificationListener實現：

 

import java.io.Serializable; 

import javax.management.Notification; 
import javax.management.NotificationListener; 

public class MyListener implements NotificationListener, Serializable{ 


    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 

    public void handleNotification(Notification notification, Object handback) { 
     System.out.println("objecto "+ notification.getMessage()); 

    } 
}

在此先感謝。 Andres。

問題是您的JBoss服務器在其類路徑中沒有您的監聽器實現（ar.com.cube3.test.msn.MyListener），所以它不能實例化它將其註冊爲監聽器。將所有自定義類（如偵聽器）打包到jar中，並將該jar放入目錄[jboss-home]/server/[server-name]/lib。

尼古拉斯一些信息，是的，你是對的，我的錯誤，我認爲這是沒有必要把罐子到lib文件夾時的類已經在耳邊。 – aivaldi 2010-10-18 13:30:12
