All Implemented Interfaces:

EventListener

public class XMPPBridge
extends EventBridge

An EventBridge implementation based on XMPP protocol and Smack XMPP client library. What's good about XMPP (Extensible Messaging and Presence Protocol, an IETF standard protocol that grew up from Jabber IM) is that generally it has fewer or no deployment limitations (unlike JMS and JGroups that are generally a good solution for local controlled networks). Also it provides lots of additional information for free, such as presence, and much more.

This implementation is based on Smack XMPP client library from JiveSoftware.
