Java Systemd Service on Debian Jessie

Systemd

Make sure systemd is installed.

systemctl

This command should list all installed services.

You need to add the Backports repository where the OpenJDK 8 package is located.

Add the file /etc/apt/sources.list.d/backports.list with this content:

# Backports repository
deb  http://ftp.debian.org/debian jessie-backports main contrib non-free

(You may replace http://ftp.debian.org/debian with any closer mirror, or even http://httpredir.debian.org/debian.)
