Problem in file association and main-class in JWS

Question

Hello , all
I have a problem in JWS with file association and main-class. I have a java application that has two entry classes, one is appmain.class that is required to launch from web, and the other is player.class that is required to launch when user double-click the .abc extension file.
In JWS 5.0+, there is a association element in JNLP syntax that can be used to make the file association with .abc extension. But how can I declare the main-class in JNLP file?
If I declare the application-desc element as <application-desc main-class="player">, the player.class will be launched from web. But if I declare it as <application-desc main-class="appmain">, the .abc extension wil be associated to the appmain.class.
Does anyone know how to solve this problem? Thank you for your kindly help.

One way is to define a third main that refers
to the other two, as appropriate. E.G. if the
web based main does not include -open as
its arguments, it is easy.class WebStartSpringboard {
  /** Call web based main unless args include -open. */
  public static void main(String[] args) {
    if (args[0].equals("-open") ) {
      OpenFileBasedClass.main(args);
    } else {
      WebBasedClass.main(args);
}Other measures might be taken for a situation
where the web based version does include a
-open argument.
