Copy the service script and paste it. Then save the file.

ATTENTION: I'm not a extremely experienced linux user, so there can be some code/command mistake. I just share the code for the people there can't create a service script by them self.

I'll share my SystemD service Config. When he is don't need a startscript. Works fine for me.

When you need to creating SystemD service we must create a file. In this case we're going to writting this command:

nano /usr/lib/systemd/system/jts3servermod.service

and copy all script include changes on: WorkingDirectory, ExecStart and User. It is just important where is our files and .jar file as our launcher.

[Unit]
Description=JTS3ServerMod
After=network.target

[Service]
WorkingDirectory=/home/ts3bot
User=ts3bot
ExecStart=java -mx30M -jar /home/ts3bot/JTS3ServerMod.jar &
TimeoutSec=300
RestartSec=15
Restart=always

[Install]
WantedBy=multi-user.target



After changeing script and source files we saving file content. And all is done.
Everything when we should doing to launching script is 2 important commands.
1. we need enable service by command: systemctl enable jts3servermod
2. now time to launching our service writting: systemctl start jts3servermod

And that's all.

ps. Everything about SystemD services can be found here

I switched to Ubuntu 16.04 LTS and had to rewrite my JTS3ServerMod boot script. Sry it was a little bit too late. First I created one and then "oh ... lets search in the forum" 

(So it is tested for Ubuntu 16.04 LTS)

So I found two ways to start the bot. Each one has its benefits:

First way:
Execute is by using the new jts3servermod_startscript.sh from Stefan


Pro:
- Uses technology from stefan
Con:
- Is not having any benefits from SystemD


Code:

[Unit]
Description=JTS3Servermod
# add mysql.service or postgresql.service depending on your database to the line below
After=network.target mysql.service
Before=shutdown.target reboot.target halt.target


[Service]
WorkingDirectory=/home/tsbots/JTS3ServerMod_HostingEdition/
ExecStart=/home/tsbots/JTS3ServerMod_HostingEdition/jts3servermod_startscript.sh start
ExecStop=/home/tsbots/JTS3ServerMod_HostingEdition/jts3servermod_startscript.sh stop
Type=oneshot
User=tsbots
Group=tsbots
RemainAfterExit=yes


[Install]
WantedBy=multi-user.target


Second way (my prefered):
Execut is directly by using java command


Pro:
- Benefits like "Restart" is possible and used (as soon as the service stopps without systemd stop command it restarts again)

Maybe someone is interested in this code - I use the upper one for all my programs/tools which already have good old sysvinit start scripts (never change a running system)
