Cancel A Selected task in ServiceManger

Question

Cancel A Selected task in ServiceManger
How can I cancel only a single task without affecting the other tasks in the delivery plan ?
The following will allow you to cancel any tasks having a supervisor, without affecting the remaining tasks in the Plan.
1. Assign a supervisor for any plan task you may want to cancel. Do this in the Plan tab/Participants sub-tab.
Assign the supervisor from any of the 3 methods - Person/Queue, Position, or Expression.
2. In Site Administration, set to ON the Configuration Tab setting for Allow Task Supervisors To Cancel Tasks.

Answer 1

you could develop a subclass of Timer that stores a list of all scheduled TimerTask instances. Then retrieve the instance that you want to cancel:
TimerTask [] tasks = timer.getScheduledTasks();
tasks[0].cancel();
.... you would have to make sure it works (that the TimerTask is actually canceled and not executed), but the code would be easy- just over-ride each schedule method so that it adds the current TimerTask argument to the list of all tasks... .... I would imagine that sun has a reason for not providing that functionality. They may want to avoid security concerns about having a separate Object cancel tasks- or perhaps the reason has some thing to do with how the tasks are schedule on the machine.... ... you might be able to find an answer in the source code of Timer or TimerTask (src.jar in your SDK folder).
