摘要
Web服务为运行在不同平台上应用程序之间的协作提供了一种机制。传统的Web服务构建于中心化的体系结构。P2P网络具有去中心化、自组织等优点。越来越多的学者开始研究基于P2P网络的Web服务发布与发现方式。阐明了Web服务的概念及其体系结构。介绍了JXTA的协议及其资源的发布和定位方式并提出在JXTA网络中实现Web服务的处理流程。解决了传统的Web服务基于中心化架构的弊端。同时,利用JXTA平台提供的安全机制可以实现Web服务调用过程中的消息传输安全性和完整性以及身份认证。
Web service provides applications running on different platforms with interoperability. It is based on a centralized architecture. P2P network takes edvantages of decentralization, self - organization etc. More and more scholars begin to study how to deploy and discover Web services based on P2P network. Illustrate the idea of Web service and its architecture. Introduce JXTA platform and its approach of deploying and locating services. Put forward a process model for implementing Web service on a JXTA network. Overcome the shortage of centralized mechanism used in traditional Web service architecture. Security, integrity and identification for messages used in Web service invoke process can be implemented by the JXTA platform.
