title: Exception while making dockbar hook
body: <p>I tried to customize the default dockbar in liferay. </p>
  
  <p>I can reflect my changes into dockbar. But when I login first time after restarting my server, it is giving me exceptions below:</p>

  </code></pre>
  
  <p>These errors continuously repeat recursively and stop after some seconds. It shows some license file is missing. </p>
  
  <p>I can't figure out what's the reason behind it.</p>
  
  <p>I already put license_warning.jsp file with the view.jsp file, still it is firing this exception.</p>
  
  <p>The functionality is working fine for me, just giving loop of exception in the log/console as first time user login.</p>
  
  <p>Thanks,
  Ankit</p>
