Abstract: Web service as a new mode for Web application has become the hotspot research in software engineering. The Web service technology provides a technical framework to integrate and co-operate numerous applications on heterogeneous platforms. Web services composition, which is composed of a number of basic services, is designed to implement complex business logic. This paper presents a lightweight Web services composition architecture based on SOAP and WSDL. It also shows how the architecture is used to solve the problems of integrating the data and applications on the navigation co-scheduling project for the Three Gorges-Gezhouba Dams.

Key words: Web services composition, XML, SOAP, WSDL, applications integration

摘要： Web服务作为一种新兴的Web应用模式受到了软件工程领域的广泛关注，其提供了一个解决异构平台上的应用之间连接、集成和互操作的技术框架。Web服务组合是将多个服务组合成一个能完成复杂商业任务的技术。该文给出了一种基于SOAP/WSDL的轻量级Web服务组合构架，用其解决了三峡—葛洲坝水利枢纽通航调度项目中异构平台上的数据和应用的整合与共享问题。
