The Design And Implementation Of A Stateful Web Services Container

While building an open and scalable integration framework for system design tools is becoming one of the key technologies in the realization of distributed collaborative-development, using Web services technology and wrapping the modules of design tools as Web services can satisfy the requirements of distributed collaborative applications. Therefore, it is important to provide a reliable service runtime environment for the framework.Since the existing Web services containers have major problems in scalability and service development efficiency, a combinative and dynamic extended Web services container, RCSWSC, is proposed in this paper with a dynamic language module, which uses Python embedding technology to separate the implementation of container process and services function and obviously improves the development efficiency. The container can deploy the stateful Web services to provide basic support for process restore in the collaborative developments by adding a resource state management model based on WSRF (Web Services Resource Framework).Moreover, a series of problems is analyzed in this paper caused by single SOAP protocol binding, and a SOAP protocol dynamic binding framework is designed and implemented, which can support the dynamic transmission for SOAP message exchange. Besides, a SOAP dispatch algorithm on the basis of customer satisfaction is presented as well.The practical application reveals that RCSWSC can reduce the coupling between the container and services development, and promotes the efficiency of service development and stability of service operation.
