Towards Transaction-Based Reliable Service Compositions

When a user requests the execution of a process in a service environment, often she desires transactional behavior in executing. However, current standards for Web services execution do not offer support for transactions. We overcome this shortcoming by presenting an extension proposal for integrating transaction management into the BPEL framework. The proposal has been demonstrated by a drop-dead order system in the context of the automotive industry. We test the business behavior described by BPEL specifications with and without transaction management when failures occur. Experimental results show that the proposed extension to BPEL framework is a viable solution for incorporating transactions into BPEL processes in order to implement reliable business processes.
