How to run java service as a non-root user on CentOs 6

Question

I have a script that starts java application as a service on CentOs 6. Here it is:

#!/bin/sh
# chkconfig: - 80 20

SERVICE_NAME=cn4server
PATH_TO_JAR=/usr/local/share/myserver/cn4server.jar
PID_PATH_NAME=/usr/local/share/myserver/cn4server-pid
case $1 in
    start)
        echo "Starting $SERVICE_NAME ..."
        if [ ! -f $PID_PATH_NAME ]; then
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is already running ..."
        fi
    ;;
    stop)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stoping ..."
            kill $PID;
            echo "$SERVICE_NAME stopped ..."
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
    restart)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stopping ...";
            kill $PID;
            echo "$SERVICE_NAME stopped ...";
            rm $PID_PATH_NAME
            echo "$SERVICE_NAME starting ..."
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
esac

It works well, but there is a problem: it runs as a root. How can I change the script to run java application on behalf of another user?

Check out cron's `@reboot` shortcut and put it in the respectives user's crontab. — Markus W Mahlberg, Jul 10 '14 at 07:40
I tried but unfortunately cron's @reboot doesn't work for non-root user on CentOs. Here is some explanation: http://unix.stackexchange.com/questions/109804/crontabs-reboot-only-works-for-root — Fedorov7890, Jul 10 '14 at 15:21
Finally crontab worked. It was my mistake passing wrong arguments. — Fedorov7890, Jul 11 '14 at 06:36

The solution for me was: crontab for a non-root user with the line @reboot /usr/local/share/myserver/cn4server.sh restart

It workes fine, although it's a workaround.
