Hi, I am able to invoke jBPM workflow from java using processInstance.signal(); This is not a blocking call. Is there any function call that will block the client thread until workflow is ended or stopped. Or is there a call back handler that I can use to implement this functionality. -Harshit View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4210723#...
