start-stop-daemon and javaFX program

Question

this is driving me crazy, please could you help with the start-stop-daemon to start a javafx jar file, where I need to issue the following command to start it

sudo /opt/jdk1.8.0/bin/java -Djavafx.platform=eglfb -cp /opt/jdk1.8.0/jre/lib/jfxrt.jar:/home/pi/prayertime/JavaFXApplication4.jar javafxapplication4.JavaFXApplication4 &

and the start_stop_daemon script is as follows

#!/bin/sh
#
# init script for ship-it
#

### BEGIN INIT INFO
# Provides:          ship-it
# Required-Start:    $remote_fs $syslog $network
# Required-Stop:     $remote_fs $syslog $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: init script for the ship-it box
# Description:       We'll have to fill this out later...
### END INIT INFO
