The Study And Implementation Of P2P Web Service

The Web Service is a new calculation model rised in recent years, which basedon XML,SOAP and other basic techniques,at the same time, P2P and it's variousapplications has gradually prevailed in our lives with it vivid structure,lowexpenses,high-efficiency and so on. Combined two advantages subtly, thisthesis,which use the discretization of p2p to enhance the flexibility of WebService,designed a model of publishing Web Service in p2p network, and it carryout the publishing and requesting Web Service in p2p network ,through combiningthe resources of Advertisements, Pipes, modules etc in p2p network. Enventuallythe application, programmed on JXTA platform provided by Sun Microsystems Inc,implement the Web Service's publishing and requesting in P2P network, in whichsome Web Service's technical specifications,such as XML,SOAP,WSDL ect,were beingused.Adopted the fast development tool Jbuilder8.0, the application carry out theprocession of a service's publishing and requesting with the packages of JXTA2.0and the classes programmed by myself.This service is deployed in the local throughApache Axis1.2RC2,meanwhile Tomcat5.0.5 act as the service's servlet containers.The application implement the Web Service's publish and request on P2P networkin the end.This paper introduces the technical specifications related with the WebService, such as: XML, SOAP, WSDL, and the process and principles of Peers'scommunication via Pipe on JXTA network. At the same time, this paper particularlydescribed how to carry out the Service's publishing through Advertisements on JXTAnetwork. Combined above-mentioned techniqueses,This thesis designed some classesgathered the functions of Service's publishing and Peers's communication, throughwhich the application carry out the Service's publishing,the establishing ofcommunicate pipe and so on.Finnaly,it blend the Web service in P2P network.
