How to run a .jar application as a service (Start on boot of system)
Ok I'll make this quick. I'm developing a client-server app with an Ubuntu 17.04 server as the server. In that server is a jar containing all the server-side code.
The code just binds some sockets and continuously listen for client requests and makes threads for each request.
The problem is, that I can't get the .jar to startup on system boot. I check this by checking for open ports and none of the ports I coded in ever listen on boot up.
I've tried the following
Startup Applications - didn't work
Systemd - the .sh script works perfectly when I run it nornally, .jar runs and the ports open, but when booting up nothing happens. Using sudo service bla bla bla start also runs the app perfectly. It just won't work on boot up
The target specified is graphical.target and the unit starts AFTER mysql.service
Using init.d - jack shit happens
I'm at my wits end on what to do. Please help, thanks.

i) Create your bash script called mystartup.sh to run the .jar file in /etc/init.d/ directory(login as root)
# vi /etc/init.d/mystartup.sh
ii) Add commands to this script one by one:
#!/bin/bash
echo “Setting up customized environment…”
fortune
iii) Setup executable permission on script:
# chmod +x /etc/init.d/mystartup.sh
iv)Make sure this script get executed every time Debian Linux system boot up/comes up:
# update-rc.d mystartup.sh defaults 100

A simple way is provided by the upstart package, after installing it just save the following script in etc/init/onshutdown.conf :
# /etc/init/onshutdown.conf
start on starting rc RUNLEVEL=2
# execute single command
exec /bin/sh /path/to/mystartup.sh
# alternatively without an extra script
script
java -jar /path/to/jarfile.jar
# your commands here
end script
Replace 2 with your preferred runlevel(s) (e. g. [2345]). For more information about upstart see man 5 init and the upstart cookbook.
