Re: [Wrapper-user] Wrapper starts and stops immediately

Winston,
Your application appears to be starting up correctly, but the
Wrapper's shutdown
hook is being started by the JVM. This is most likely happing because
something is
calling System.exit.
Can you review your application source, add some debug output and trace
what is going on?
From what I can see, your application's main method is being called and
completes normally. What happens inside, I am not able to see from this
output.
Make sure that your even thread is NOT a daemon thread. Make sure that
the top level run method of that thread is catching all errors and
logging them.
Cheers,
Leif
