基于Web服务的动态工作流系统的研究与实现

分析了面向服务的计算环境及服务组合的新特征和新问题，并在此基础上从面向业务用户的角度对基于Web服务的动态工作流进行了探讨，提出一种基于Web服务的动态工作流模型。以该模型为基础，设计了具有三层结构的基于Web服务的动态工作流系统，按照该架构并基于J2EE平台实现了系统．对基于web服务的动态工作流应用提供了系统支撑与验证环境。

The Research and Implementation of Business-end Service Composition System

Service composition, as an emerging paradigm in service-oriented environment, has shown huge potential in supporting for Internet-based cross-enterprise business process integration. Through the analysis to new features and open issues of service-oriented environment and service composition, a Web services based dynamic workflow model is proposed to raise the abstraction level of service composition by extending the traditional workflow model with service concepts. Based on the model, a Web services based dynamic workflow system with three-layers architecture is put forward and a prototype is also developed to facilitate and experience business process integration based on J2EE.
