I=92m trying to daemonize a java class that=92s doing some mail routing =
and built jsvc for that purpose.  The source I used is from the =
commons-daemon-1.0.15-src downloaded from the Apache site, and I=92m =
presuming that it=92s good code.  I grabbed a Linux style start/stop =
script off the web and modified it for my path and class, etc (shown =
below).  When I run in debug, I can clearly tell that jsvc finds the =
commons daemon.  But, it can=92t find my class included in =
eMailRouter.jar.  As far as I can tell, I have the path to the class =
correct and I tested it by calling from Java rather than jsvc using this =
command:

java -cp =
/usr/share/java/commons-daemon-1.0.15.jar:/home/rtanner/Java/Workspace/eMa=
ilRouter/eMailRouter.jar org.linfield.eMailRouter.RouterDaemon=20

Since I added an otherwise unnecessary main method that simply prints =
out =93I=92m in main=94, I was able to confirm that I had found and =
executed the class file.    My class implements Daemon and at this point =
really does nothing more (each of the required methods simply print out =
their name).  So is it possible that my problem could be the class =
itself rather than the start/stop script.  Would it help if I posted the =
Java source for the class?

Immediately below is the start/stop script:

#!/bin/sh

# Setup variables
EXEC=3D/usr/local/bin/jsvc
export JAVA_HOME=3D/usr/java/jdk1.7.0_55
export =
CLASS_PATH=3D/usr/share/java/commons-daemon-1.0.15.jar:/home/rtanner/Java/=
Workspace/eMailRouter/eMailRouter.jar
CLASS=3Dorg.linfield.eMailRouter.RouterDaemon
USER=3Droot
PID=3D/tmp/example.pid
LOG_OUT=3D/tmp/example.out
LOG_ERR=3D/tmp/example.err

do_exec()
{
    $EXEC -debug -home $JAVA_HOME -cp $CLASS_PATH -user $USER -outfile =
$LOG_OUT -errfile $LOG_ERR -pidfile $PID $1 $CLASS
}

pwd
echo $CLASS_PATH
echo $JAVA_HOME

case "$1" in
    start)
        do_exec
            ;;
    stop)
        do_exec "-stop"
            ;;
    restart)
        if [ -f $PID ]; then
            do_exec "-stop"
            do_exec
        else
            echo "service not running, will do nothing"
            #exit 1
        fi
             ;;
    *)
            echo $"usage: daemon {start|stop|restart}" #>&2
              exit 3
            ##  ;;
esac
exit


Thanks.
