| 摘 要： | 论文提出了一个基于工作流方法的WebServices集成框架模型,分析了该模型中控制流、数据流、异常流的功能组成部分。通过对工作流概念模型中应用层、工作流层、服务层和信息层等分解和协作,应用WebServices商务处理执行语言(BPEL4WS)技术,着重探讨了工作流具体实现和异常流的触发过程,提高了松散藕合环境下的Web服务集成范围。最后,论文以实例展示了架构的可行性。

| Abstract: | In this paper we describe an architectural model of workflow-based Web Services Integration in a loosely coupled environment,which have four parts such as workflow,control-flow,data-flow and exception-flow.Based on the analysis of conceptual of workf/ow composed of application layer,workflow layer,service layer and message layer,we focus on the principles and implementations of workflow as well as exception-flow using the BPEL4WS specification.As thus,it enhances the flexibilities and scalabilities of Work/low-based Web Services Integration.Finally,A actual example is shown in the paper. |
