How to start java service automatically when Centos server starts up

Question

I have a server running CentOS, which I am configuring and I would like to have a java service startup automatically when the server is restarted how can I go about doing this?

The command to run the service is:

java -jar testing.jar

this is located in folder /sys/java/service.

Also being new to Linux how can I actually kill the service if I need to?

Solution

Put the command in /etc/rc.local

the best option would be running it as a dedicated user as in

su - username -c "java -jar /sys/java/service/testing.jar"

you can kill the service then with

pkill -u username java
