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

Question

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

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

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
