Abstract: This paper shows how processes based on web services modelled with XPDL can be executed. For the execution, an open-source workflow engine called Open Business Engine (OBE) was extended with capabilities for calling web services and for being called by web service clients. We describe the architecture of the orchestration system and also some implementation details. Since the process model can be generated with ProSpec, the work is based on [1], the previous article in this issue.

Keywords: web services; workflow languages; XML; workflow management; business process modelling.
