addNotificationListener in interface NotificationRegistration
Parameters:
name - The name of the MBean on which the listener should be added.
listener - The listener object which will handle the notifications emitted by the registered MBean.
filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
handback - The context to be sent to the listener when a notification is emitted.

                             throws InstanceNotFoundException
Description copied from interface: MBeanInterceptor

Adds a listener to a registered MBean.

A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.

The listener object that receives notifications is the one that is registered with the given name at the time this method is called. Even if it is subsequently unregistered, it will continue to receive notifications.

Specified by:
addNotificationListener in interface MBeanInterceptor
Parameters:
name - The name of the MBean on which the listener should be added.
listener - The object name of the listener which will handle the notifications emitted by the registered MBean.
