The BIS-Grid project, a BMBF-funded project in the context of the German D-Grid initiative, focusses on realising Enterprise Application Integration using Grid technologies, enabling small and medium enterprises both to integrate heterogeneous business information systems and to use external D-Grid resources and services with affordable effort. The goal is to provide proof of concept that Grid technologies are feasible for information systems integration, and to enable business users to utilise and participate in the D-Grid, facilitating a more sustainable Grid infrastructure in Germany. One technical part of BIS-Grid is to provide a WS-BPEL-based workflow engine that is based upon the Grid Middleware UNICORE 6, and that is capable to integrate stateful Web Services, so-called Grid Services. In this paper we present a generic extension to UNICORE 6 that allows to use an arbitrary WS-BPEL engine, in our scenario the WS-BPEL engine ActiveBPEL, and standard WS-BPEL to orchestrate stateful Web Services in a transparent and scalable manner.
