JBoss MBean 通知监听器问题

Question

我在 JBoss 上的NotificationListener 上遇到了一些问题。

我在 JBoss 上有一个 MBean，我可以连接并调用他们的方法。但是，当我尝试添加通知时，您会遇到下一个异常：

我正在 JBOSS 之外的客户端调用 MBean

，主要代码是：

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();
        }

通知监听器实现：

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());

    }
}

提前致谢。 安德烈斯.

Answer 1

问题是您的 JBoss 服务器在其类路径中没有侦听器实现 (ar.com.cube3.test.msn.MyListener)，因此它无法实例化它以将其注册为侦听器。将所有自定义类（如监听器）打包到一个 jar 中，并将该 jar 放入目录 [jboss-home]/server/[server-name]/lib 中。
