The Integrated Research Of P2P Network And Web Service

P2P is a new technology in the network computing area, which arms to connect all different computers in the net so that resources can be shared and transferred among them, and use all inactive resources. All of the network nodes are peers to peers, and they are both client and server in the P2P network architecture. P2P implements the sharing of computing resources and services through the direct communication among the peers.WebService is a new platform to build distributed and interactive applications. These self-containing, self-describing and modular applications can be described, published, found and invoked by the web client in the network. Based on special rules, WebService can interact with other compatible modules and execute specified tasks.P2P and Web Service will be applied widely in the future. It is certain that there are interoperable applications between the two technologies. In order to implement the combination of the P2P network and WebService, this thesis has analysed the P2P technology and Protocols of JXTA firstly, then analysed the WSDL, UDDI, SOAP technology etc, with the WebService. Arming at the questions such as differences between the bottom layer protocol and transmission message form, this thesis has studied the combination of P2P and WebService.In this thesis, the way of proxy has been introduced into the JXTA P2P Network, that make the JXTA's applications can interoperate with the WebService. Broker that work as the intermediator needs to implement both the rules of JXTA and WebService. During the deployment of the Broker, this thesis uses the WSDL2Java tool to produce the client code of WebService automatically. Those codes will be used to invoke the WebService by Broker. At last, in order to inspect and verify the basic method of the combination of the two technologies in this thesis, an instance of WebService has been developed and integrated into the JXTA P2P network, and the Peers invoke transparently the P2P Network exterior WebService has also been realized.Thus achieved the both technologies integration.goal.
