This paper discusses problems of Grid service composition using BPEL4WS. In particular, difficulties concerning the invocation of WSRF-based services are elucidated. A solution to this problem is presented by extending the BPEL specification, and an implementation based on the ActiveBPEL workflow enactment engine is described.
