【摘要】 为提高Internet环境下通过Web服务合成方法构建的跨企业应用系统的灵活性和复用性,分析和研究了面向Web服务的商业流程执行语言(BPEL4WS)中存在的不足,讨论了将商业逻辑从商业流程中分离的必要性。提出从BPEL4WS中提取商业逻辑的思想,同时利用.NET架构下的事件处理技术对其进行了实现,从而有效地改善了BPEL4WS的完全面向商业过程、将商业逻辑隐含在过程中而造成的合成后的Web服务灵活性差及不能有效复用的缺点。最后通过实例证明该方法的可行性。更多还原

【Abstract】 In order to improve the flexibility and reusability of the application systems integration across enterprises in the internet with web service composition,the shortcoming of the business process execution language for web service(BPEL4WS) is analyzed and the necessity that business logic should be separated from business process is discussed.So the idea of extracting business logic from BPEL4WS is put forward and implemented with.net event technology.As a result,this technology solve the problem of lacking flexibility and reusability of web service composition due to the fact that business logic is underlying business process,which is resulted from the fact that BPEL4WS is a full process-oriented method.Finally,an example is given to prove the feasibility.更多还原
