Abstract :
When solving problems such as enterprise information integration and interoperation across heterogeneous repositories, Web services and workflow are extensively used. Due to the nature of modularity, openness and encapsulation, traditional exception handling strategies can hardly meet the demands in the Web service setting. In this paper, we put forward a strategy based on constraint rules of Web services and the position of service nodes. We also design a framework to support exception handling dynamically during the execution of workflow.
