2.4.1 Local Notification Listeners

In the simplest case, listeners are objects in the same application as the broadcaster MBean. The listener is registered by calling the addNotificationListener method on the MBean. The MBean server exposes the same method so that listeners can also be added to an MBean identified by its symbolic name.

In Figure 2–2, one listener has registered directly with the MBean and another has registered through the MBean server. The end result is the same, and both listeners receive the same notifications directly from the broadcaster MBean.
