[jboss-user] [jBPM] - Re: JBPM and Webservice call with callback - please advise

For this you should use boundary timer events that is attached to a task. It has capability to cancel task that is attached to and continue with alternative path. Take a look http://mswiderski.blogspot.com/2012/07/service-task-with-web-service.html here, it describes runtime engine support for web service invocation.
