  org.jmx4odp.j4oNet.MBeanResolver
      org.jmx4odp.j4oNet.BroadcastResolver

All Implemented Interfaces:

javax.management.MBeanRegistration, MBeanResolverMBean

public class BroadcastResolver
extends MBeanResolver

This object takes request for jmx service reolution, and broadcasts it as a UDP packet that a J4ONet object listing on the same broadcast group and port will reply to. This is the version 1 of the J4ONet discovery protocol. If this object were to generate another version stamp, the current system would ignore it. It then listens for x ms (BroadcastReplyTimeout in the config jso) for UDP replies sent by J4ONet.
