Introduction to BPEL. By the way, last
year, I saw a demo of Niyamas Elixa BPEL Engine and was extremely
impressed. Very nice suite using standard J2EE technologies, with easy integration with other applications using web
services (BPEL4WS) and a BPEL Workflow Designer that can rival Visio, implemented in cross-browser DHTML and Javascript --
it has to be seen to be believed. Unfortunately, they don’t have a screenshot on their site.
