A critical and time-consuming part of service computing is the handling of exceptions that may occur during service composition process and composite services execution. This paper aims to design a framework of exception handling for service-oriented computing. According to the exception classification and exception handling strategies introduced in this paper, the exception handling process is described. The description method of exceptions is based on the predication logic and statechart. Predication is used to define concepts and statechart is used to describe the execution process of composite Web services. The exception handling strategies are described formally according to how and when the exception handling actions are executed. This framework includes three functions: exception detection, exception diagnosis and exception recovery.
