title: NoClassDefFoundError on external library project for Android
body: <p>I use eclipse for Google Android development.</p>
  
  <p>I've created a library project (<code>[x] Is Library</code> in the Android-settings), which includes an external jar-file (Referenced Libraries). This library project are referenced in another Project (the actual project which will use the library project). This is done by add the project under the Android-settings.</p>
  
  <p>the source compiles but if I want to execute it on the device, I get the NoClassDefFoundError for a class which is <strong>inside the jar-file which is included in the library project</strong>.</p>
  
  <p><strong>Edit:</strong> The jar-file ist added to the exported entries (<code>[x] my.jar</code> on the <code>Order and Export</code>-Tab from the library project)</p>
  
  <p>Is there a clean way to get this working?</p>
