Web服务正在成为一种整合发布在网络上的松散耦合服务方法的标准。因此,web服务的高可靠性和在发布错误的服务结构的情况下的可用性面临挑战。然而当前web服务的中间层只提供非常有限的错误检测和回复机制。本文为满足web服务的容错性和稳定性的要求,提出了一套可扩充的回复机制用以处理和回复web服务组合中出现的典型错误。实验表明这种方法能有效的提供可靠的的web服务。
Web services are becoming a standard for integrating loosely coupled service methods that are released on the web. Therefore, the high reliability of web services and the availability in the case of the wrong service structure are challenged. However, the current web service middle tier provides only a very limited number of error detection and recovery mechanisms. In order to meet the requirements of web service fault tolerance and stability, this paper proposes a set of scalable reply mechanism to process and reply the typical mistakes in web service composition. Experiments show that this method can effectively provide reliable web services.
