Jessie has moved away from sysvinit and onto systemd. Writing an init script to /etc/init.d/ is outdated,
and a bit tedious since you have to handle the start/stop/restart logic yourself (if you want those capabilities).

New Method:

1. Write a unit file for systemd.
$ sudo nano /etc/systemd/system/your_jar_software.service
