Policy-based exception handling for BPEL processes

Aiming to improving the exception handling capacity of BPEL process, this paper explores a policy-based exception handling method for BPEL processes. The paper propose a policy-based exception handling description language EHPDL-P, and design a framework to support the implementation mechanism of exception handling process based on EHPDL-P. Finally, through a case study from the domain of Manufacturing Execution System, this paper demonstrates the policy-based exception handling approach for BPEL processes.
