摘　　要：Web Service分为无状态的和有状态的两种,网格服务实例中有些也是特殊的有状态的Web服务实例,而直接开发网格服务的难度较大,因此可以开发特殊的有状态的Web Service实例来增加网格服务的功能。介绍了Web Service的相关知识,开发了两个Web Service服务实例并部署到tomcat中,同时在GT4环境下部署网格服务,并用MathService服务实例测试部署情况;将两个Web Service服务实例部署到网格服务的容器中,并编写客户端程序测试服务的运行情况,观察结果说明可以通过开发特殊的Web Service服务实例来增加网格服务的功能。Web service divides into two kinds： the stateless and the stateful, grid service examples have some specially stateful examples of Web service, and it＇s difficult to develop the grid service directly, therefore some specially stateful examples of Web service can be devel- oped to increase the function of grid service. The correlative theories of Web service are introduced. Two Web service examples are developed and deployed in tomcat. Meanwhile, the grid services are deployed in GT4 environment and the results are tested by the MathService example. Then two Web service examples are deployed in the container of grid service. The client program was designed and the service status are tested . The testing results show that the grid service functions are enhanced by the special examples of Web service.
