To enact adaptive and cross-platform workflow

BPEL4WS is a standard used for enacting Web service-based workflow, but Web service is not intelligent and cannot respond to environment changes, so Web service-based workflow is static. Currently, agent-based workflow's support for cross-platform is less than satisfactory. This paper advances that if agent is wrapped as Web service and then we can enact Web service and agent-based cross-platform adaptive workflow.
