Re: [Wrapper-user] How do I prevent wrapper from re-starting after exit ?

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Leif:

I have added the wrapper log, below.

The way this program works is that it has a built in timer that exits the 
program after 2 minutes. It started at 21:55 and exited about 2 minutes 
later. I deleted all the ping-ping stuff between the start and stop.

I have commented out
#wrapper.single_invocation=TRUE
#wrapper.on_exit.default=SHUTDOWN

in the configuration, but I made no other changes (other than 
wrapper.debug=true).

You can see that the JVM restarted the application after it shut down.

Any ideas about this?
