Re: [Wrapper-user] Wrapper ending after running Timer (TimerTask) once as a service

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

David,
    From your log, the Wrapper is exiting because it has determined that 
all non-daemon
threads have terminated.  You mentioned that you tried running your 
program with
the timer thread set as a daemon and as a non-daemon.  Which was the log you
posted from?

    Here is the line in the log which gives the reason why the Wrapper 
is exiting the JVM:

INFO   | jvm 1    | 2005/12/15 08:58:15 | All non-daemon threads have 
stopped.  Exiting.

    Have you tried adding debug output into your Timer thread to make 
sure that it is
indeed still running?   I can't think of anything that would be 
different in this case about
running as a service vs running in a console.
    Is it possible that an exception is being thrown that is causing the 
timer thread to be
terminated?   Is there any code which would be preventing any exceptions 
from being
logged?
    I usually do the following in my runner threads just to make sure 
that they never exit
without me knowing about it.  (I use a logging tool however)

public void run() {
    System.out.println( "Runner started." );
    try {
        while( !stopping ) {
            // Loop
        }
    } finally {
        System.out.println( "Runner terminated" );
    }
}

Cheers,
Leif
