How to make port 8080 free for Tomcat in ubuntu 20.04 LTS

Question

I am using Ubuntu 20.04 along with JDK-8.
I have installed Tomcat9 for making Web Application in net-beans but when ever i start tomcat9 it shows port 8080 is busy. I ran following command

# netstat -tulpn | grep 8080

and killed the process using

# kill -9 <process_id>

but after that when I start tomcat9 it shows the server port 8080 is already in use. and I again killed the process but another process again starts on port 8080 immediately and I can't start the Tomcat9.

I tried by changing port number but still error is same.

Can anyone tell me where's problem occurring and what should i do now?

@DusanBajic when I run `sudo lsof -i :8080`, every time it shows that this process is running by Command **JAVA** with some **PROCESS_ID** by User **TOMCAT**. — joy, Feb 20 '21 at 15:48
Workaround: Change the config file in Tomcat to listen on another port. — Basil Bourque, Feb 20 '21 at 17:46

This is most likely a service configured to be restarted if it crashes.

Figure out what sits on the port and disable the service or remove the package completely.
