摘　　要：当前进行Web服务编排的首选标准流程语言是BPEL4WS。在流程编排过程中,除了关注正常情况下的流程定义场景,如何清晰、快速地描述BPEL流程中出现的异常也同等重要。文中把数据库领域的ECA技术用于BPEL异常流程定义中,通过对实际业务流程进行分析,把流程中出现的异常分支都映射成ECA规则;此外,提出了BPEL规范中的异常定义元素与ECA元素的对应关系;在上述工作的基础上,实现BPEL异常流程的快速定义。通过对电信企业的施工过程进行分析,验证了该方法的可行性。BPEL4WS was the preferred language for Web Service Orchestration. In addition to defining normal processes, it was important how to describe exceptions during the execution of BPEL processes more clearly and quickly. ECA rules of database fields was used for defining BPEL exception handling in this paper. All the exceptions during the execution of business processes were analyzed and mapped according to ECA rules. It was proposed about mapping between activities about exception handing and ECA elements. BPEL exception handling were defined based on the above work. An example about installing process of telecom industry was given to prove the feasibility.
