[daemon] Stop and force-stop with jsvc
Hi,
I'm using Apache Commons Daemon and jsvc to run my Java program as a daemon
on GNU/Linux, using Daemon interface.
I'd like to have two "stop" actions:
- a simple "stop" which cancels new tasks and waits for the completion of
active tasks on my application, and then stops;
- a "force-stop", which cancels new tasks, interrupts the active tasks,
and stops.
Is there a way to do this with Jsvc? When I use "jsvc -stop ...", the
method stop() in my class implementing the Daemon interface is called, and
I have no choice to "force-stop". Could you please suggest a way to solve
my issue?
Thanks,

Sure.
BTW, on second thought perhaps the best solution would be to call
signal followed by stop. Signal method could set the flag for stop
method making it "force-stop".
Think this would be safest method, cause signal() alone causing shutdown
could lead to auto restart.

You can implement user signal (SIGUSR2) interface which will call signal() method
and there you can do what you wish. But I didn't tried to stop the JVM.
