I tried ((TaskInstance)taskMgmtSession.findTaskInstances("b").get(0)).getToken().end(); instead of ((TaskInstance)taskMgmtSession.findTaskInstances("b").get(0)).getToken().signal(); but then the result comes as a1 0 b1 1 What I require is that the task should be proceeded and as the second task is assigned to Actor "a" then the result should come something like this a1 1 b1 0 Thanks in advance CSJakharia View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4156241#...
