title: Netbeans IDE8 Glassfish 4, GlassFish Server: Administrator port is occupied by null
body: <p>I just downloaded Netbeans IDE7 with the Glassfish 4.</p>
  
  <p>I just made a project to test it out and see how it goes, and I got this error right from the start: </p>
  
  <pre><code>Could not start GlassFish Server: DAS port is occupied while server is not running
  [location]: Deployment error: Could not start GlassFish Server: DAS port is occupied while server is not running
  See the server log for details.
  BUILD FAILED (total time: 1 second)
  </code></pre>
  
  <p>I have reinstalled it three times, with the Glassfish and without and then later add it to Netbeans, i changed the domain.xml <code>name="admin-listener" port="4848"</code> to something different</p>
  
  <p>i did this cmd code <code>netstat -aon | find ":80" | find "LISTENING"</code> and closed the programm.</p>
  
  <p>i ran as administrator i think i did almost everyting but it wont simply run, and it keeps returning to the same error</p>
  
  <p>usually i would have given up but this software is required for a school project.</p>
  
  <p>i will try everything.</p>
  
  <p>i hope someone can help me.</p>
  
  <p>Thx in advance</p>
