OGSA(Open Grid Services Architecture) is called the next generation grid architecture. We study the architecture of OGSA,and program a grid service in the grid environment.How to wrap the conventional distributed software components by using Web Services,wrap the services provided by the isomerous components as automatically as possible,we make the users to visibly realize their business logical framework and integrate the WS component.From the angle of component, this system is exactly a multiple component,which provides services to external users in the Web Service mode.With the growing number of Web Services,it is necessary to compose the existing Web Services dynamically according to the service requests.A dynamic composition service method is proposed based on keywords, according to the real-time user demand changes, to promote user programming.Through analyzing the characteristics of primal Web Services composition we propose a dynamic programming model based on key word matching.
