Hi,
How to receive remote notifications using
RemoteNotificationListenerSupport?
I used it as the following:
class MyListener implements NotificationListener {
RemoteMBeanServer remote;
ObjectName objectName;
public myListener() {
// init remote and objectName

RemoteNotificationListenerSupport support
= new RemoteNotificationListenerSupport(this);
remote.addNotificationListener(objectName, support,
null, null);
}
// .....
}

THe MBean started correctly on adminserver. When I start
managedServer,
I got the folloing exception ("Null listener") from
MBeanServer on weblogic AdminServer:
