Re: [Wrapper-user] Service starts, app runs once, then shutdowns?

[Leif M. <le...@ta...>]

Russell,
The restart functions are really only designed to restart a JVM which 
"fails" in any one
of a number of ways. It sounds like in your case, the Java application 
is completing
without problems and exiting normally. The Wrapper is handling this 
correctly by exiting.

Is there a reason why you don't just create a thread within your JVM 
that runs an
operation every 15 minutes? This way the JVM stays up. That would have the
disadvantage of having the JVM take up memory while it is idle...

One way that you could make this work is to add the following configuration
properties to your wrapper.conf file.

wrapper.on_exit.0=RESTART
wrapper.restart.delay=900

See the following:
http://wrapper.tanukisoftware.org/doc/english/prop-on-exit-n.html
http://wrapper.tanukisoftware.org/doc/english/prop-restart-delay.html

That should override the default shutdown behavior and queue up a 
restart when
the JVM exits normally. Let me know how this works as I didn't actually 
try it just
now...

You might want to use a different exit code to trigger the restart so 
you have a
way to actually cause the cycle to stop. Use System.exit(1) or something.

Cheers,
Leif
