The Design and Implementation of Unified Invoking Component Based on Web Services Framework

Abstract

Web Services is a platform which enables the applications interoperate on the Internet. It is widely used in designing and building systems in open and dynamic distributed environments such as EAI (Enterprise Application Integration) and B2B (Business to Business). As the development of framework technology, it is convenient and standardized to use framework to develop web applications. For Web Services, the frameworks Axis, Axis2, XFire and CXF are widely used. By the performance testing of the four frameworks, this paper not only introduces the four framework but also analyzes the differences of the four frameworks, and then makes some suggestions for developers to choose the appropriate one. The framework can simplify the development process and decrease the development time. However, because of the differences of the frameworks, the interoperation between different web service's server and client may cause incompatible problems. This paper analyzes the reasons of this incompatible problems and finally presents a mechanism based on unified invoking component to solve this problems. By parsing and repacking the SOAP messages, the incompatible problems between client and server can be solved successfully.
