Hi Phillip, In general, it is trivial to take an existing java -jar command and systemd-ify it. All you need to do is to run it as an ExecStart in the foreground in the systemd unit file, possibly with a User setting. Something like this should work:
[Unit] Description=My stream app [Service] User=unprivileged_user Restart=always ExecStart=/usr/bin/java -jar ... [Install] WantedBy=multi-user.target systemd will send a SIGTERM to the java process by default when you invoke systemctl stop. As a bonus, you also get log management of stdout/stderr via journald.
