Abstract: In the current SOA implementation, Web services can not collaborate with each other. In order to work collaboratively, the component in the SOA must have the awareness about the activities in the system. This paper adopts an event infrastructure, which introduces the Event Driven Architecture(EDA) into the SOA. This event infrastructure collects execution information of the Web service, uses the complex event processing technology to process this information, and sends it to the SOA component to realize collaborative awareness.

Key words: Service Oriented Architecture(SOA), Web service, collaborative awareness, complex event processing, event driven architecture

摘要： 在现有面向服务架构(SOA)实现中，Web服务之间无法直接协同。为了完成协同工作，SOA的各个构件必须具有对系统全局的感知能力。该文采用一个事件信息组件，在SOA中引入事件驱动架构，搜集各个Web服务的调用信息，利用复杂事件处理技术对其进行整理后，发送给SOA构件订阅者，达到协同感知的目的。
