Research And Implementing Of Middleware Supporting Reliable Composition Of Web Service

Along with the prompt development of the Internet technology and application, Web Service technology has become a trend. It can decorate the existing function with the uniform interface, and make applications cross different platform to communicate with each other. On the other hand functions become more and more complex, and applications change from B2C to B2B, which make the composition of Web Service become the destiny of Web Service technology.The composition of Web Service means more distributed. One composition of Web Service may cross several different companies or organizations, although there is only one little interface. Then how to make sure the reliabilities of the composition would be a great problem. Now, there are several methods to describe the composition and a few protocols about the Web service transaction. But, there are few middlewares which can support the reliabilities of the composition of web service so far.This paper will produce a whole framework of a kind of middleware which can support the reliabilities of composition of web service, and analyze this framework from several aspects such as the definition of composition of web service and the execution of composition of web service. This framework also has a lay-based model to manage the web service transaction during the execution of the composition of web service and can support the nested composition of web service. At last the paper will give a simple production of the prototype of the system, and analyze an application by using the framework.
