title: Why eclipse always complain that the tomcat server port is in use?
body: <p>I have a eclipse web project source code, the name of the project is "My-Proj" . </p>
  
  <p>I download Eclipse Java EE version (Indigo) , extract the achive, then I started the eclipse IDE. After I successfully installed tomcat7 server into the Eclpse IDE. I import my existing project to Eclipse IDE.</p>
  
  <p>Then I run my imported project by choose "Run on server", but eclipse pop up the error message window like below:</p>

  <p>I saw the port has been used, so I change the server running port by double click on tomcat server V7 under Eclipse "server" tab, and change the port to <strong>8085</strong> as below (see the right side of the image):</p>
  
  <p><strong>Please right click the image and view the image if you can not see clearly.</strong>

  <p>I run the project on server again , but I got the same error, port 8080 is in use, why? <strong>I have changed the port number to 8085, why it still complain the port 8080?</strong></p>
