Summary

Not only is JabberTM a cross-platform, open source server platform for instant messaging, but most importantly, it is a powerful platform for XML messaging and presence. Since the protocol is capable of supporting so much more than instant messaging, Jabber has been suggested as becoming the "dial tone of the Internet." This book will offer programmers a chance to learn and understand the Jabber technology and protocol from an implementer's point of view. Every detail of every part of the Jabber client protocol is introduced, explained, discussed, and covered in the form of recipes, mini- projects or simple and extended examples in Perl, Python, and JavaTM. Programming Jabber provides a walk-through of the foundation elements that are common to any messaging solution, including a detailed overview of the Jabber server architecture.

Author Biography

DJ Adams is an old SAP hacker who still thinks JCL and S/370 assembler are pretty cool. In recent years he's been successfully combining open source software with R/3 to produce hybrid systems that show off the power of free software. He's the author of O'Reilly's Programming Jabber book, contributes articles to O'ReillyNet's P2P site, and has to own up to being responsible for the Jabber::Connection, Jabber::RPC and Jabber::Component::Proxy modules on CPAN.
