We've used Strophe to implement a pure-javascript/html chat like this (with an XMPP server on the other end, and jetty handling proxying of non-blocking asynchronous comet long-polling requests to the XMPP server). XMPP supports this natively via its HTTP binding specification, and there are free open source servers such as openfire that will work with Strophe out of the box. http://code.stanziq.com/strophe/ http://code.stanziq.com/strophe/ http://www.igniterealtime.org/projects/openfire/index.jsp http://www.igniterealtime.org/projects/openfire/index.jsp
