Business Flows with BPEL4WS BPEL4WS is now moving rapidly into becoming the de facto standard for Web service orchestration with most platform vendors following in IBM and Microsoft footsteps after the submission of the specification to OASIS. This increased momentum and visibility will drive a great need for educating developers on how to put BPEL to work. This article illustrates a payment flow example coded using BPEL, highlighting some of the main constructs of the language and demonstrating how the flow can be monitored and managed once it is deployed. The example can be extended in various ways to include more advanced language constructs. Such extensions will be illustrated in subsequent articles.

BPEL Unleashed

BPEL (Business Process Execution Language) makes business processes and composite Web services first-class citizens of the Java and .NET platforms, while preventing vendor lock-in. The result is a drastic reduction in the complexity, delivery time, and cost associated with implementing workflow, BPM (business process management), and related business integration projects. BPEL is a new standard for implementing business processes in an emerging service-oriented architecture world. As such, applying BPEL introduces new considerations, challenges, and pitfalls for delivering process... (more)
