About the BookJXTA is a new technology that enables us to build peer-to-peer systems - systems that enable computers to discover one another and co-operate together across the Internet. This kind of interaction characterizes some of the most interesting networked applications that have appeared in the last year: Napster, Gnutella, Morpheus, and their relatives. In these systems, a user installs a client program, which discovers other installed clients on other machines, and communicates with them - allowing the sharing of files between computers. This peer-to-peer architecture is a completely new paradigm in software design, representing a totally different approach to the standard client-server frameworks used in almost all the distributed systems that currently exist. JXTA aims to provide a set of technologies that allow programmers to develop clients and services that can interact in this way, without having to implement all of the elements that make up such a system themselves. Aspects such as discovery of peers, advertising presence, penetrating firewalls, and transferring data, which are common to all peer-to-peer applications, are handled by a set of standard libraries that are available to a JXTA application. Early Adopter JXTA teaches the experienced developer all they need to know to be able to play confidently with JXTA. It will show how to use JXTA as the foundation for developing a peer-to-peer application, and in the process explain how to think and design in a peer-to-peer way, and hopefully inspire you to come up with the ideas for the next generation of peer-to-peer applications. The code in this book makes use of the JXTA reference implementation, and is written in Java, although the principals discussed will be just as relevant to other implementations in other languages. About the ChaptersChapter 2, "JXTA Basics," examines the basic components of JXTA, and shows how they are implemented on top of interoperable protocols. It describes how to configure the JXTA platform for peers that are either on the Internet or an Intranet, and how to use the JXTA shell to perform basic interaction between peers. The most frequently used API packages within the Java implementation of JXTA are also covered, as well as how to perform discovery of peers, peer groups, and pipes, how to create and work with advertisements, how to manipulate XML-based messages, and how to create and work with JXTA pipes.
