Rule-driven exception handling approach for Web Service composition
一种规则驱动的Web服务组合例外处理方法

A ride-driven exception handling model for Web service composition was proposed. The semantic of the model was specified in detail too. The nile in the model is based on event, activity state and meta-process. Meta-process is invoked by relevant rides as controlling and coordinating mechanism for base processes. The proposed model can not only be used for failure recovery, but also be used for more complex situations such as process modification. The advantages of this approach are modularity, extensibility and adaptability.
