title: Having trouble exporting runnable JARs from Eclipse
body: <p>Jar available at <a href="http://dl.dropbox.com/u/10919879/roller.jar" rel="nofollow">http://dl.dropbox.com/u/10919879/roller.jar</a></p>
  
  <p>After writing and testing my program with Eclipse's built-in run Utilities, I decided it was time to export and distribute. So I go to File>Export>Runnable JAR and designate the class whose main method I want to invoke. Everything seems to be going off without a hitch, until I try to actually run the JAR.</p>
  
  <p>Error: Could not find or load main class C:\Users\Matt\Documents\My Dropbox\Publ
  ic\roller.jar</p>
  
  <p>Contents of roller.jar</p>
  
  <pre><code>dice/Roller$RollData.class
  dice/Roller.class
  META-INF/MANIFEST.MF
  </code></pre>
  
  <p>contents of META-INF\MANIFEST.MF:</p>
  
  <pre><code>Manifest-Version: 1.0
  Class-Path: .
  Main-Class: dice.Roller
  </code></pre>
  
  <p>What's going on, and how do I fix it?</p>
