Advanced Concepts in WS-BPEL 2.0

Waruna and I’ll be doing a post-conference tutorial session on “Advanced Concepts in WS-BPEL” in WSO2 Con 2011.
Summary of the session is as follows.

BPEL is the de-facto standard for modeling executable Web services orchestrations. It is an XML-based language used for the definition and execution of business, as well as scientific work flows using Web services. WSO2 Business Process Server (WSO2 BPS) and Apache Orchestration Director Engine(ODE) are two WS-BPEL compliant business process executable work-flow engines, which support composition of Web services by orchestrating service interactions.
In this tutorial, Warauna and I will elaborate on some advanced concepts in WS-BPEL 2.0 and extensibility in WSO2 BPS like
  • fault handling
  • compensation handling
  • event processing   
  • selective event processing
  • multiple event processing
  • concurrent event processing
  • message correlation
  • parallel processing
  • Introduction to ODE extensions
  • Future improvements with extensions
