Actually I saw WS-HT specification, it says that after reassignment the task status changes from Reserved to ready and so the task could be claimed by on of the declared as potentiel owners or groups.But the limitation is when task is reassigned ,the only way to notify for that change is to send an e-mail. In fact ,I would like to know if there any way to call a custom java service or method when the task is reassigned ( status changes from reserved to ready).that why I am asking if it is possible to catch the event that is responsible for changing task status after timeout.

The class in charge of deadlines and escalation is: https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human... https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human... Starting from line 187 is where the escalation logic takes place. It would be good to have a pluggable mechanism to add custom logic here. Something similar to WIHandlers, but for the HT server.

It is definitely provides me the solution how to customize escalation event . Actually here is the solution I set up according to what you explained before , it is working fine  and  I am giving the java code that can help other members  to define quickly a customized escalation. Just for information , I do not  use the Servlet HumanTaskServiceServlet  in my application as mechanism for plugging cutomized task service. Actually I am using spring configuration on my application , so at startup I am creating the task service using the code below : public void initialize(){ MyOwnEscalationHandler Myhandler = new MyOwnEscalationHandler(); taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener(),Myhandler);// register my handler in the task service } The class MyOwnEscalationHandler is the following *public* *class* MyOwnEscalationHandler *implements* EscalatedDeadlineHandler { @Override *public* *void* executeEscalatedDeadline(Task task, Deadline deadline, Content content, TaskService service) { // *TODO* Auto-generated method stub *if* ( deadline == *null* || deadline.getEscalations() == *null*) { System.+out+.println("**********No escalation detected**********"); *return*;         } *for* ( Escalation escalation : deadline.getEscalations() ) { System.+out+.println("Deadline detected  processing action "); System.+out+.println("The task has expired , I am executing my own Deadline handler**********"); // we won't impl constraints for now //escalation.getConstraints() // run reassignment first to allow notification to be send to new potential owners *if* ( !escalation.getReassignments().isEmpty()) { // get first and ignore the rest. Reassignment reassignment = escalation.getReassignments().get( 0 );                 task.getTaskData().setStatus( Status.+Ready+ ); List potentialOwners = *new* ArrayList( reassignment.getPotentialOwners() ); task.getPeopleAssignments().setPotentialOwners( potentialOwners ); task.getTaskData().setActualOwner(*new* User("Administrator")); }       *for* ( Notification notification : escalation.getNotifications() ) { System.+out+.println("****** Notify by emaill**********"); }                    } deadline.setEscalated( *true* );         }        } Best regards, -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/803857#803857] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
