Adaptable Transaction Processing in the Web Services Domain

The advent of Web Services technologies both demands interoperability and adaptability of various transaction processing models, and provides a solid basis for this goal. In this paper we first give an overview of the problem domain and analyze the state-of-the-art Web transaction protocols, the Business Transaction Protocol (BTP) and Web Services Coordination and Transactions (WS-C/T), and then we propose an Adaptive Transaction Framework based on extensions to the CORBA Activity Service as a principled way to allow reliable and adaptable Web Services computing. Detailed examples are given to illustrate the applicability of our framework to real world Web Services transactions.
