About the White Paper:
BPEL4WS allows the definition of both business processes that make use of Web services and business processes that externalize their functionality as Web services. This short paper introduces the basic language elements of BPEL4WS based on a simple example. The concepts underlying the language are briefly explained: establishing bilateral partnerships, correlating messages and processes, defining the order of the activities of a business process, and handling exceptions via long-running transactions. We'll also look at the resulting programming model, and the usage of BPEL4WS in pure B2B scenarios. |
