摘　　要：One of the challenges that come from the development of grid computing applications is to predigest complicated process of compiling, deploying on their infrastructures and toolkits such as globus toolkit. As we explain in this article, one of the predigesting works focuses on making applications react dynamically to different infrastructures and toolkits. Since WS-resource framework （WSRF） specifications allow the programmers to declare and implement the association between Web service and one or more stateful resources, we aim at making infrastructures provide WS-Resource according to the specifications automatically by using a middleware. This paper focuses on the adapting mechanisms and adapting algorithm for WSRF in grid computing. We investigate the dynamicstatic mode for adapting, and describe how to apply it to adjust different infrastructures to provide WS-Resource based on WSRF specifications flexibly. Then we present an adapting algorithm for grid computing infrastructures to provide interfaces conforming to alterable uniform specifications. This paper explains the adapting algorithm in detail and lists it out. In order to examine whether our idea is valid, we took some experiment on current grid computing infrastructures and virtual ones. First experimental results showed the gain that could be expected from the use of such a middleware.
