'port 8080 is already in use and no process using 8080 has been listed

I am trying to start Tomcat from Eclipse, but a problem occured:

Port 8080 required by Tomcat v6.0 Server at localhost is already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

I tried to list processes connected to this port using command on Windows: 

netstat -aon

But on the listing there is no process with PID = 8080. I also tried: 

netstat -aon | find "8080"

But it also didn't find anything. Can anyone help me?

Open eclipse go to Servers panel, right click or press F3 to open Overview window and go to Ports (Modify the server ports). You will get the following:

tomcat adminport
HTTP/1.1
AJP/1.3

You can change the port numbers (e.g. HTTP/1.1 port number 8080 to 8082).

In windows " wmic process where processid="pid of the process running" get commandline " worked for me. The culprit was wrapper.exe process of webhuddle jboss soft.

If no other process is using the port 8080, Eventhough eclipse shows the port 8080 is used while starting the server in eclipse, first you have to stop the server by hitting the stop button in "Configure Tomcat"(which you can find in your start menu under tomcat folder), then try to start the server in eclipse then it will be started.

If any other process is using the port 8080 and as well as you no need to disturb it. then you can change the port.

In my case, there was a conflict with the virtualization function of Windows 10. This problem occurred after installing Hyper-V, virtual machine platform, and hypervisor platform to use hyper-v, docker, and bluestack together. Even if I check with netstat, it is not a port in use, and even if I restart Windows and change the port, it does not start up saying that it is in use for all ports. So, by changing the following services to Disabled in Windows Services, the Tomcat problem was solved, but bluestack, docker, etc. execution became impossible. After starting Tomcat, when I manually changed the services again, bluestack was executed.

Hyper-V Host Compute Service
HV Host Service
Host network service
Network virtualization service
