title: Running JavaFX application for ARM
body: <p>I've spent nearly a day trying to figure out why when I run a JavaFX .jar on my Raspberry Pi, it wont open up the UI. I'm sure its something with my command to launch it. I've been working off of this tutorial:</p>
  
  <p><a href="https://wiki.openjdk.java.net/display/OpenJFX/OpenJFX+on+the+Raspberry+Pi" rel="nofollow">JFX on Raspberry Pi</a></p>
  
  <p>But cannot figure out what the "stopwatch.mainscreen" argument is for at the end.</p>
  
  <pre><code>/opt/jdk1.8.0/bin/java -cp Stopwatch.jar stopwatch.MainScreen
  </code></pre>
  
  <p>thanks for any help you smart smart people can provide!</p>
