Summary

O'Reilly's pioneering reference is the first and last word on JXTA, the hottest new distributed computing technology. JXTA in a Nutshell delivers all the information developers need to get started, including an overview of P2P distributed computing, an explanation of the JXTA Project's new platform, and ways that developers can become a part of the development effort. JXTA in a Nutshell introduces major concepts in a hands-on way by explaining them in context to the shell, and contains a complete reference to the JXTA application bindings. Also included is the full JXTA protocol specification. The book also covers important topics such as security, and how the JXTA technology fits into the standard Java classes.
