摘　　要：One of the challenges that come from the development of Grid Computing applications is to predigest complicated process of compiling, deploying on the infrastructures and toolkits such as Globus Toolkit. As we explain in this article, we think it is essential to find the solution for rapid Grid Computing applications development. GBuilder is just such a tool we worked out for rapid develop on extant Grid Computing infrastructure platforms. By using GBuilder, applications should be able to react dynamically to different infrastructures and toolkits. Since WS-Resource Framework （WSRF） specifications provide technique standard to developers to declare and implement the association between Web service and one or more stateful resources, we aim at making infrastructures provide WS-Resource according these specifications automatically by adding a middleuaare. This paper focuses on the adapting mechanisms that are provided as the lowermost component of GBuilder. First we study the adapting model for Globus Toolkit in patterns of combination dynamic and static. Then it describes how to apply the dynam-static adaptation flexibly to adjust different infrastructures to provide WS-Resource based on WSRF. At last, it comes along the conclusion and we give out our future works.One of the challenges that come from the development of Grid Computing applications is to predigest complicated process of compiling, deploying on the infrastructures and toolkits such as Globus Toolkit.
