碩士 === 國立中央大學 === 資訊工程研究所 === 91 === As Web Services raise, and many enterprises make use of it to interoperate with Web Service of other companies. The underlying message protocol between Web Services is based on XML, and the XML-based messages enable the communication between heterogeneous platforms. Because of modularity, Web Services are much reusable than other application. However, how to compose existing Web Services to a more powerful composite Web Service is an issue. In this thesis, we develop a composite service engine that uses BPEL4WS (Business Process Execution Language for Web Service) as the composite service description language, and propose the architecture of the engine. The architecture includes following mechanism and technique: 1.Composite service deployment 2.BPEL document paring 3.Composite service lifecycle control 4.Composite service execution flow control
