A novel workflow engine for Web service orchestration, JBPM4WS is proposed in this paper. JBPM4WS is built on JBPM, a well-known workflow engine. We extend the workflow language JPDL, which is adopted by JBPM, to support service invoking. JBPM4WS engine adopts four-layer architecture, and is implemented based on some open-source frameworks, such as Hibernate, CXF and JAXB.
