title: RuntimeException from xmlbeans - can't find compiled schema
body: <p>I'm getting a RuntimeException while executing some code that depends on generated xmlbeans classes. I can't figure out if this is:</p>
  
  <ul>
  <li>me missing something during code-generation or packaging</li>
  <li>a runtime dependency missing</li>
  <li>a misleading error message, and I should be looking elsewhere.</li>
  </ul>
  
  <p>The xbean.jar version is the same in the build and execution environment. Anyone seen this before or have any ideas?</p>
  
  <p>Thanks.</p>
