Re: [Wrapper-user] getting exit code from JSW/integ method 3

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

Brent,
    I just went back and tested this with the latest code.  If your 
WrapperListener.start
method returns new Integer( 9 ) then the Wrapper correctly exists with 
an exit code of 9.
Looking more closely now, I also see that your wrapper.log file confirms 
this as well.

    Where are you seeing an exit code of 1 or 2?  The problem may be 
that the Wrapper
process itself is returning an exit code or 9, but the application you 
are using to start
the service is returning 1 or 2.  That is a different process.  How are 
you starting the
service from your java application?

    The Wrapper captures all console output from the JVM and sends it to 
the Wrapper's
console output as well as to the wrapper.log file, depending on the 
wrapper.conf.
    Once again, you may not be seeing the output because you are looking 
for the output
of the application that is being used to launch the service and not from 
the service itself.

    You may need to create another marker file on service exit to get 
that information
back to your controller application.

Cheers,
Leif
