Question

我在运行我的 CN1 项目

时收到此错误

java.lang.NoSuchMethodError: javafx.scene.web.WebEngine.setUserDataDirectory(Ljava/io/File;)V

我使用了侧边栏菜单，但错误出现在主屏幕上这是我的 SateMachine.java

  @Override
protected void beforePortada(Form f) {
  WebBrowser browser=new WebBrowser();
    f.setLayout(new BorderLayout());
    f.addComponent(BorderLayout.CENTER, browser);


    String URL= "someurl.php";

    String ssurhtml = "somehtml";

    ConnectionRequest req = new ConnectionRequest();
    req.setUrl(URL);
    NetworkManager.getInstance().addToQueueAndWait(req);
    byte[] data = req.getResponseData();
    if (data == null) {
        //throw new IOException("Network Error, try again later.");
    }
    //JSONParser parser = new JSONParser();
    // Map response = parser.parseJSON(new InputStreamReader(new ByteArrayInputStream(data), "UTF-8"));


    XMLParser xmlParser=new XMLParser();
    Element element= null;
    try {
        element = xmlParser.parse(new InputStreamReader(new ByteArrayInputStream(data), "ISO8859-1"));
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    Element element1=element.getElementById("somediv");
    String test= String.valueOf(element1);

    char c= '\'';
    char r= ' ';

    test=test.replace(c,r);
    test=(ssurhtml+test+"</body></html>");
    browser.setPage(test,null);
}

我收到错误信息，模拟器显示黑屏

当前模拟器中存在回归问题，需要 Java8。请尝试升级到 Java8 以解决此问题。
