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?
PID is the process ID - not the port number. You need to look for an entry with ":8080" at the end of the address/port part (the second column). Then you can look at the PID and use Task Manager to work out which process is involved... or run netstat -abn which will show the process names (but must be run under an administrator account).
Having said that, I would expect the find "8080" to find it...
Another thing to do is just visit http://localhost:8080 - on that port, chances are it's a web server of some description.
