Contributed by HTTP and XML, Web service is becoming the component called through the Web. In this article, we describe and analyze some current distributed object technologies,and then introduce the emerging Web Service technology. We introduce and analyze the two software strategies: Microsoft . NET and Sun ONE. Web Services will transform the current isolated Internet Web into interconnected services.展开更多
