You need to use the form which is passed in from the execute()
method signature.
DynaForm dForm = (DynaForm) form;
dForm.set("author", "test");
return mapping.findForward("success");
This assumes you are using the same form for your setup and processing
action and you are forwarding to the page which renders the form.
