У меня есть сайт, URL которого начинается с "Http: //» но это дает мне исключение с сообщением - Неподдерживаемый протокол: https. Возможно ли, что сайт использует протокол HTTPS, но его URL начинается с "Http: //» и не "https: //».

public ActionForward executeAction(ActionMapping mapping, ActionForm form,
              HttpServletRequest request, HttpServletResponse response)
      throws Exception {

    ActionForward forward = mapping.findForward(Constants.SUCCESS);
    String link = "http://abc.fgh.jkl.mno";
    URL thisURL;
    HttpURLConnection conn = null;
    try {
        thisURL = new URL(link);
        conn = (HttpURLConnection) thisURL.openConnection();
        System.out.println(conn.getResponseCode());
        System.out.println(conn.getResponseMessage());
        } catch (Exception ex) {
        ex.printStackTrace();
    }
    return forward;
}
