Solution. To fix it, append a & symbol to the end of the command, it executes the Java program in the background, and continue until it finished.
You can try this:
#!/bin/sh
nohup java -jar /web/server.jar &
The & symbol, switches the program to run in the background.
The nohup utility makes the command passed as an argument run in the background even after you log out.

Find your user defined services mine was at /usr/lib/systemd/system/
Create a text file with your favorite text editor name it whatever_you_want.service
Put following
Template to the file whatever_you_want.service
[Unit]
Description=webserver Daemon
[Service]
ExecStart=/usr/bin/java -jar /web/server.jar
User=user
[Install]
WantedBy=multi-user.target
Run your service
as super user
$ systemctl start whatever_you_want.service # starts the service
$ systemctl enable whatever_you_want.service # auto starts the service
$ systemctl disable whatever_you_want.service # stops autostart
$ systemctl stop whatever_you_want.service # stops the service
$ systemctl restart whatever_you_want.service # restarts the service
If you're using Ubuntu and have "Upstart" (http://upstart.ubuntu.com/) you can try this:
Create /var/init/yourservice.conf
with the following content
description "Your Java Service"
author "You"
start on runlevel [3]
stop on shutdown
expect fork
script
cd /web
java -jar server.jar >/var/log/yourservice.log 2>&1
emit yourservice_running
end script
Now you can issue the service yourservice start
and service yourservice stop
commands. You can tail /var/log/yourservice.log
to verify that it's working.
If you just want to run your jar from the console without it hogging the console window, you can just do:
java -jar /web/server.jar > /var/log/yourservice.log 2>&1
Run in background and add logs to log file using the following:
nohup java -jar /web/server.jar > log.log 2>&1 &
