Abstract

Recently many business applications embrace Web services as their implementation technologies Due to the long duration and loosely coupled properties Web service based applications require more transactional supports beyond traditional transactions Some initial work has been done to deal with the transaction aspect of Web service applications in form of standards or protocols Among these efforts compensation is commonly used for backward recovery However the compensation mechanism adopted is too fixed and cannot satisfy the various requirements of different applications In this paper we propose a flexible compensation mechanism which enables flexible compensation schemes for a single failed case Based on a thorough analysis of current Web service compensation protocols and standards we extend the flexible compensation mechanism to the Web service computing environment The implementation of the extended compensation mechanism is discussed and the incorporation of the mechanism into current standards is also addressed
