基于Web Services 工作流管理系统的研究与应用

分析了工作流产品和技术在应用环境中所面临的模型内容有限、不能满足流程多样性的要求、柔性差、模型很难扩展、模型缺乏对分布环境的支持等问题,提出一种基于Web Services的工作流管理系统的实现方式;详细讨论了其体系结构、工作流引擎模型的设计;选择J2EE开发环境,借助JBuilder 9.0为开发平台,采用WebLogic8.11作为应用服务器,数据库采用Oracle 9i,采用客户端 Session Bean CMP的多层开发模式设计了一套供水企业营业管理系统。该系统具有运行可靠、高效、使用方便、可扩展和易维护的特点。

Study and Application of Workflow Management System Based on Web Services

On the basis of the research of workflow technologies and products in application environments,this paper presents a way to realize Web based workflow management system.All most all of the existing workflow products have some blemishes.Such as the model content is limited,can't satisfy diverse process request,feebleness scalable and flexible,the model can hardly to be expand,lacks support to distributed environment,redefinition is very difficult.The structure of the system and the design of its workflow engine model are also elaborated.Choose the J2EE development environment,use JBuilder 9.0 as developing language,adopt WebLogic 8.11 for applied server and the Oracle 9i is the best database of our work,build customer the Session Bean CMP to make the many tiers framework.Develop an application system for water supplement enterprise.The new business system is reliable,efficient,convenient and easy to maintain.
