The reason I posted this is that there have already been questions regarding this and since I did not spent a lot of time with jBPM 4 and certainly not the pvm part, it took me some additional time to figure this out. In general I do want to compliment everybody for the (imo) good docs. At least the depth and completeness, which leaves the correctness ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4235312#...
