interupting long runnning things is not different in jBPM then in any other java application. Make actionhandlers that can receive events (non-jbpm events) and act upon them. Have your timer send one of these events then.. But it might be a nice addition to jBPM I think to be able to cancel long running async things when they are already running (timers can be cancelled when not started yet) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4220021#...
