A flexible approach for exception monitoring and handling in web services

Abstract

It has a significant application value to provide new value-added services by combining existing services in the web services environment. The way how to monitor the process of composite service execution is a very important issue. Exception handling plays not only an important role in process modeling and model optimization, but also a key procedure which process implementation and management depended on. In this paper, we present a flexible framework for exception monitoring and handling in web services, which is a run-time monitoring methods based on user monitoring requirements for web services and supporting a variety of handling strategies for exceptions. Under this model, we also put forward the operations and rules for exception monitoring and handling, which is customizable and flexible for services combination. The implementation is carried out and the result shows the proposed method can monitor and improve the quality of service flexibility to achieve the operation of the service.
