    }

    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        Locale r = (Locale) request.getAttribute("localeObject");
        return r == null ? request.getLocale() : r;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
}
