You don't have to have a large file. I use the dispatching to
organize in a sort of "controller" fashion delegating processing to
other files. I do this when I have an AdministrativeAction, for
example. I use separate classes not unlike the way you use
instantiations of Action subclasses in your model. The difference is
merely that I use non-Actions, as follows:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException,
ServletException {
ActionForward forward = null;
try {
forward = method(this,mapping,form,request,response);
} catch (Exception e) { }
return forward;
}
public ActionForward guestApplicationExit (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException {
return new
AdminActionGuestApplicationExit().execute(mapping,form,request,response);
}
........[many methods calling classes left out here.........................
public ActionForward webmasterView (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException {
return new
AdminActionWebmasterView().execute(mapping,form,request,response);
}
}
