Can Apache Daemon be used to restart a Java application if it is forcibly shutdown?

Question

I'm looking into Apache Daemon to help me with a Java app, and I just wanted to get some ideas/hints about what is possible.

I want to create a simplified application that shows some kind of failsafe ability. The application will go through 4 steps in a sequence (imagine that it prints out to a simple text file in each step just a letter, like step 1 is "A", step 2 is "B" , etc), and I would like to be able to forcibly shutdown the JVM, then have it automatically restart the java application and resume the printing out (imagine it like a child pulling the plug on the TV and it turns on again by itself).

Is this possible to do via Apache Daemon? If so, how would I automate that? Do I need to attach some third-program at the operating-system level (like a simple C program that itself monitors the flow ?).

At this stage I'm just looking for pointers, as I realize it is not really clear what I will do. I prefer Windows, but I do have a Mac also and would be open to using Mac if that is better(I know Linux has some unique tools/abilities ). Any tips/ideas appreciated.

So far, I have tried using this tutorial here for help, which has been useful but not as thorough as I need.

On windows, last time I check it was not managed by procrun (commmons-daemon) but by the windows service management.

You probably need to configure the service recovery after the daemon installation

• sc failure %SERVICE_NAME% reset= 60 actions= restart/30000
• sc failureflag %SERVICE_NAME% 1

where %SERVICE_NAME% is ... your service name

the resume logic should be in your application

Edit : add more context

See https://commons.apache.org/proper/commons-daemon/procrun.html for the service installation on windows

when issuing the commands (manually or with a cmd script)

ex :

set SERVICE_NAME=myService
prunsrv //IS//%SERVICE_NAME% --DisplayName="Test Service" \
    --Install=prunsrv.exe --Jvm=auto --StartMode=jvm --StopMode=jvm \
    --StartClass=org.apache.SomeStartClass --StartParams=arg1;arg2;arg3 \
    --StopClass=org.apache.SomeStopClass --StopParams=arg1#arg2

add the recovery settings after the service installation

ex

sc failure %SERVICE_NAME% reset= 60 actions= restart/30000 
sc failureflag %SERVICE_NAME% 1
