Jabber is a set of protocols expressed in XML, and an extensible framework that allows people and applications to exchange all sorts of information, from simple text messages to being used to extend the backbone of an enterprise data system. Jabber gives you the power to build applications that have identity, presence, and that can take part in conversations.Programming Jabber offers developers a chance to learn and understand the Jabber technology and protocol from an implementer's point of view. Detailed information of each part of the Jabber protocol is introduced, explained, and discussed in the form of mini-projects, or simple and extended examples. Programming Jabber provides this foundation by:

• Showing you how to install and configure the Jabber server
• Providing a detailed overview of the server architecture and configuration options
• Covering the core Jabber technologies such as XML streams and Jabber identifiers
• Referencing all of Jabber's XML namespaces
• Examining the client registration and authentication phases
• Showing how to deploy your own Jabber-based messaging solutions
• Demonstrating how to embed XML-RPC-style call mechanisms into Jabber
