Jini and JavaSpaces Application Development demonstrates real-world usage and application of the Jini technology. Specifically the book presents and builds on the concept of a "virtual development center." It will use the concepts of distributed development, open-source, virtual corporations, and the borderless world as a backdrop to developing products and services using Jini and JavaSpaces technologies.
