Tool Support for BPEL Verification in ActiveBPEL Engine

Abstract

The BPEL is designed for integrating and orchestrating Web services and it provides the profound solution to model business process relying on Web service platform. ActiveBPEL is a commercial-grade open source implementation engine for BPEL. In this paper, we describe the work on tool support for the BPEL verification in ActiveBPEL. We implement the algorithm of the mapping from BPEL to timed automata, and integrate it into the ActiveBPEL. By using model checker UPPAAL engine, ActiveBPEL is enhanced and can verify the BPEL properties, such as deadlock and reachability. Moreover, those timed properties of BPEL specification can be checked in our framework as well. Some case studies are presented to show the usage of verification functionality in ActiveBPEL.
