It is possible to create a timer dinamically in an ActionHandler. We wrote this
method to do this:
| public static void createTimer(TaskInstance ti, String name, Date duedate,
String actionName)
| {
| Token tk=ti.getToken();
| Timer timer=new Timer(tk);
| timer.setName(name);
| timer.setDueDate(duedate);
| timer.setAction(tk.getProcessInstance()
| .getProcessDefinition()
| .getAction(actionName));
| timer.setGraphElement(ti.getTask().getTaskNode());
| timer.setTaskInstance(ti);
|
| DbSchedulerService schedulerServ=new DbSchedulerService();
| schedulerServ.createTimer(timer);
| }
|
The key is the use of the DbSchedulerService to register the Timer and actually
getting it to work. The idea, of course, is that you can get the duedate from
wherever you need.
Finally, about how to get a processinstance's timers, you can always build your
own HQL query to get them. Look for the hibernate.queries.hbm.xml file inside
the jbpm bundle to have an example of this.
Hope this helps.
