The jBPM dev forum would be a great place. I know Tom has some ideas in this area (I just know some basics ;-) ) but he's not quite sure how to implement it (afaik, but that could have changed). And yes, you are right about needing a controler, and right again about it being used atm, but afaik in fairly controled environments, not in 'just any webservice based service between random organisations' View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029185#...
