title: Glassfish There is a process already using the admin port 4848
body: <pre><code>asadmin start-domain domain1

  <p>But it shows this error. </p>
  
  <pre><code> There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server.
  </code></pre>
  
  <p>I have searched and found that it could be the hostname or that the port is used by an other application or server and actually it is used by TCP.</p>
  
  <p>I have no problem with the hostname so I've tried this solution by changing port.</p>
  
  <pre><code>  asadmin set server.http-service.http-listener.http-listener-1.port=10080
  </code></pre>
  
  <p>but it shows this error</p>
  
  <pre><code>remote failure: No configuration found for server.http-service.http-listener.http-listener-1
  Command set failed.
  </code></pre>
  
  <p>I can't understand why.</p>
