title: Can't seem to run JavaFX project in Eclipse
body: <p>I'm on Ubuntu 14.04 64-bit. I installed Oracle-8 for Java and downloaded the e(fx)clipse bundle from <a href="http://efxclipse.bestsolution.at/" rel="nofollow">http://efxclipse.bestsolution.at/</a>.</p>
  
  <p>However, now I'm running into this error message:</p>
