httpunit не работает, когда класс расширяет JFrame

Question

При попытке входа в систему https://www.okcupid.com/login с библиотекой httpunit код ниже выполняется успешно.

Если, однако, я расширяю класс с помощью JFrame, так что я могу создать пользовательский интерфейс, выполнение не выполняется. Запрос POST завершается должным образом, но запрос GET не выполняется при выполнении HtmlPage page = wc.getPage(url)

Ниже кода я поставил вывод для обоих сценариев.

Works, если Main продляет JFrame

public class Main /* extends JFrame */ { 
    static boolean isConnecting = false; 
    public static void main(String[] args) { 
     new Main(); 
    } 

    public Main() { 
     login(); 
    } 

    public void login() { 
     try { 
      /* POST */ 
      WebClient wc = new WebClient(); 
      URL url = new URL("https://www.okcupid.com/login"); 
      WebRequest requestSettings = new WebRequest(url, HttpMethod.POST); 
      requestSettings.setRequestBody("username=myLogin&password=myPassword&okc_api=1"); 
      Page redirectPage = wc.getPage(requestSettings);/* unique */ 
      Set<Cookie> cookies = wc.getCookieManager().getCookies(); 

      /*GET */ 
      wc = new WebClient(); 
      for (Cookie cookie : cookies) { 
       wc.getCookieManager().addCookie(cookie); 
      } 
      HtmlPage page = wc.getPage(url); 
      WebResponse response = page.getWebResponse(); 
      String content = response.getContentAsString(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
}

Answer 1

Я выяснил, почему это происходит и что происходит вокруг, но я до сих пор не знаю, как заставить его работать над расширением JFrame.

1. Если вы используете htmlunit для обработки запросов URL, сначала удалите расширение JFrame. Теперь код выполнит, но все равно не запустит пользовательский интерфейс.

2. Вместо использования расширения класса для JFrame, в той части, где вам потребуется расширение, создайте новый экземпляр JFrame. Затем используйте этот экземпляр JFrame для объявления всех необходимых свойств и действий.
