BPEL 100 Success Secrets - Business Process Execution Language for Web Services- THE XML-based language for the formal specification of business processes, business interaction protocols and SOA based integration
Excellent introduction to BPEL - the business process execution language. A number of Web services orchestration / process tools are based on BPEL but hide the language behind a drag-and-drop GUI. To effectively use these tools, though, you have to understand the concepts that make up BPEL - scopes, partner links, correlation sets etc. This book likely provides the best introduction to these concepts. Examples are given in raw BPEL as well as using Oracle BPEL Manager and Microsoft BizTalk. There is coverage of advanced topics, such as correlation and convoys, a great introduction to BPEL best practices. In summary, if you are interested specifically in BPEL, this is likely the book you want to get.
