I have a simple process. Start-> HumanTask->ServiceTask->HumanTask->End. I start the workflow completes the first task. Then Jbpm will give call to the service task. For the service task I have defined my Service task handler. In that handler if some exception occurs, Service task will remain pending. This means that it has failed. Now If I want to retrigger the service task so that my process should continue, is there any way to retrigger that?
