Implementation of JXTA-based P2P System Access from Web Service

An heterogeneous distributed system using middleware to finish the visit to each other between P2P and Web Service system is brought forward, and the safety and veracity of visit the service must be ensured. The blue print of middleware is to adding the function of visit Web Service onto the basic function of peer. The middleware provides the service accepting and disposal of request to the Web Service, and then it is responsible for discovering, calling service and returning result. On the basic of two heterogeneous systems visiting each other, in order to find the related service position, the UDDI is added to the middleware. In this way service can be found although simple information is given. In addition, several middleware can group as a peer group, when a common peer joins in the group service which can be provide to enlarge the scale of query and to ensure the safety of system.
