title: Java GUI in NetBeans on Mac OS X 10.8
body: <p>I'm currently studying a module at university about programming in java. </p>
  
  <p>The IDE we are using is NetBeans and I am using Mac OS X 10.8 </p>
  
  <p>We have just started making a application that utilises a GUI. </p>
  
  <p>I am following a worksheet and have followed it exactly. </p>
  
  <p>Currently I am stuck because when I run my application the project builds fine but the GUI does not open when I run it. </p>
  
  <p>My Project is built up of multiple packages and classes and I have set the GUI class as the main class. </p>
  
  <p>Even more confusing to me is that I copied the project over to my Window 7 VM and it built and ran fine and the GUI came up. </p>
  
  <p>Can anyone help as to why the GUI does not open on OS X and if there is a solution.</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I get the following exception when I try to run my app on a Mac:  <a href="http://pastebin.com/cySzY5Wr" rel="nofollow">http://pastebin.com/cySzY5Wr</a></p>
