</resources>
<application-desc

          width="300"
          height="300">

    name-class="HelloWorld"
    Attibute name should be "main-class"
    See
    http://docs.oracle.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#application_desc

    the main-class="HelloWorld" is below the application-desc tag..

    No it is not - there is name-class, not main-class. At least in the XML blob that was posted. Perhaps when you post it between \
     tags it will become readable enough that you yourself see it.
