Building BPEL Solutions - 2 days

BPEL Fundamentals Training 

Our BPEL training explains the specifics of composition, orchestration, and coordination of web services. It provides a rich vocabulary for definition and execution of business processes. By taking this training, you will gain an understanding of the BPEL specification while learning how to apply the practical use of BPEL concepts to real-world service orchestration scenarios. Tools used include JDeveloper or BizTalk Orchestration Designer, an integrated visual toolset for rapidly creating, testing and deploying composite applications based on BPEL. 

Taught by expert instructors from Genuine Belgium, BPEL Fundamentals features hands-on training and an emphasis on realistic labs and programming exercises.
