Class LoggerBroadcaster

java.lang.Object

javax.management.NotificationBroadcasterSupport

mx4j.log.LoggerBroadcaster

All Implemented Interfaces:

javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, LoggerBroadcasterMBean

public class LoggerBroadcaster
extends javax.management.NotificationBroadcasterSupport
implements javax.management.MBeanRegistration, LoggerBroadcasterMBean

This broadcaster MBean allows to redirect MX4J internal logging to registered JMX listeners.

Simply register this MBean in the MBeanServer, register one or more listener (eventually with filters on the notification type), then call (directly or through MBeanServer) one of the start operations. From this moment, MX4J internal logging is redirected to this MBean, and from here to all registered listeners, basing on their filters.
