Yes those work but what I need is when the app shutsdown for say, some error, the service stops as well. As it is the app stops running, I can see this in the log file, but the service continues to run.

This should happen because this is the way I think a service should run. Secondly if the service does not shutdown, then its difficult for us to create an automated reaction to the shutdown.
