Peer-to-peer (P2P) has progressed from a curiosity to a serious opportunity for businesses to move beyond the costs and limitations of traditional client-server based computing. With a choice of several new, maturing technologies, Java developers need a single source to explain the benefits of each technology and help them see how to fit the P2P "pieces" together - both in building new systems and integrating with existing ones. Java P2P Unleashed: With JXTA, Web Services, XML, Jini, JavaSpaces, and J2EE starts with a discussion of the P2P architecture, referencing similarities with existing, familiar systems while previewing several types of P2P applications. Java P2P Unleashed explains how to plan ahead for security, routing, performance and other issues when developing a P2P application. Each Java P2P technology is approached from a P2P perspective, focusing on implementation concerns Java developers will face while using them. The last section includes several large-scale examples of different P2P applications - managing content, building communities, integrating services, routing messages, and using intelligent agents to gather information. The final chapter looks ahead to future developments in Java P2P technologies, including the use of J2ME. Java P2P Unleashed is confidently recommended for Intermediate to Advanced level users. 752 pages.
