For modular, extensible and adaptable exception handling of web service composition, a model using meta-process is proposed in this paper. The detail semantic of the model components and their relationship are specified too. The rule in the model is based on event, activity state and case data of base process. When an exceptional event occurs, corresponding meta-process is invoked as controlling and coordinating mechanism for base processes if some rules are met. Examples analysis show that the proposed model not only can be used for failure recovery, but also can be used for more complex situation such as process modification.
