Starting of Tomcat failed, the server port 8080 is already in use

Question

Deploying on Apache Tomcat or TomEE
    profile mode: false
    debug mode: false
    force redeploy: true
Starting of Tomcat failed, the server port 8080 is already in use.

Hi I have a spring-framework based MVC project and I'm trying to build as simple CMS website.

I was working on it yesterday even though I have problems with actually running it because of my lack of understanding of the whole framework.

But today I'm getting the same message again and again even after trying solutions that fellow developers are suggesting like killing the process that's using that port via command prompt or simply changing the port number of server.xml file and even restarting my laptop which obviously didn't work.

I'm aware that I might get some hidden exception messages in apache tomcat log files but I'm not sure where to look?

Any help is highly appreciated since I'm stuck with the same message and tons of posts that suggest the same thing with different variations nothing worked so far.

EDIT:

Here is the full Apache Tomcat or TomEE message:

I see this:

Caused by: java.net.BindException: Address already in use: bind

OK, I get it but I tried killed the processes that use it still nothing, I'm going to try with TCPView

EDIT: This was when I was trying to use NetBeans, once I started using STS I don't have any problems with tomcat.

Answer 1

Try listing all the apps and their ports, and check for the one using 8080 and try to kill it or you can directly kill whatever app is using that port

The 2nd option is to change the port of your tomcat server with any available port

I hope this may solve your problem
