title: JAXB and constructors
body: <p>I'm starting learning JAXB, so my question can be very silly. Now I have classes and want generate XML Schema. Going after <a href="http://wiki.eclipse.org/EclipseLink/Examples/MOXy/JAXB/GenerateSchema" rel="noreferrer">this</a> instruction I get exception </p>
  
  <blockquote>
    <p>IllegalAnnotationExceptions ... does not have a no-arg default
    constructor.</p>
  </blockquote>
  
  <p>Yeah. My classes haven't default no-arg constructors. It's too easy. I have classes with package visible constructors / final methods and off course with arguments. What shall I do - create some specific momemto/builder classes or specify my constructors to JAXB (in what way?) ? Thanks.</p>
