Abstract
A lot of research works have devoted to automated web services composition. An important aspect of the composition procedure is exception handling. Due to the very large number of possible exceptions need to be considered, it is difficult and tedious to produce the exception handling steps manually in the composition process. However, the exception handling process has not been carefully considered in the service composition literature, let alone the automated generation of exception handling code. In this paper, we present an exception handling framework for web service composition. The framework provides a model for web service with exceptions specification. A holistic planning paradigm is also introduced to increase the expressiveness of AI planning domain. The corresponding planning algorithm is proposed to solve the holistic planning problems. We showed that the service specification can be mapped to holistic planning domain and exception handling logic can be generated automatically. A case study system is given to show that the framework is useful for the construction of a holistic interactive system.
