body: <p>I am installing SoapUI Open Source on my Linux server.</p>

  <pre><code>wget https://s3.amazonaws.com/downloads.eviware/soapuios/5.4.0/SoapUI-5.4.0-linux-bin.tar.gz
  tar -xzf SoapUI-5.4.0-linux-bin.tar.gz -C /opt/
  cd /opt/SoapUI-5.4.0/bin/
  ./soapui.sh
  </code></pre>
  
  <p>While installtion last step (./soapui.sh) is giving me following error:</p>
  
  <pre><code>05:11:16,498 INFO  [DefaultSoapUICore] All plugins loaded

      at java.awt.Window.&lt;init&gt;(Window.java:536)
  </code></pre>
  
  <p>When I use 'export DISPLAY=:0.0' , step ./soapui.sh goes in long run and need to abort manually with following message -</p>
  
  <pre><code>Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
