  Set validate="false" and do the form validation in each method that you
want validated. You could write a util method to make this less
cumbersome, but its actually not very cumbersome :)... about 4 lines of
  		ActionErrors errors = form.validate(mapping, request);
		saveErrors(request, errors);
		if (errors.isEmpty() == false) {
			return mapping.findForward(IConstants.FAILURE_KEY);
