我正在为 j2me 运行带有 eclipse pulsar 的 S60 SDK。我正在尝试加载 Linkedn 登录页面。但如果我只通过设置 htmlc.setPage() 加载linkedin.com，那么它只显示linkedin name join now &.. 但不显示电子邮件和密码文本框和登录按钮。

我的课程代码如下：

public class Login {
    Form form = new Form();
    String authorizeUrl = "";
    LinkedInUser user;

    public Form Login() {
        try {
            Display.init(this);
            HttpRequestHandler  handler = new HttpRequestHandler();// = new AsyncDocumentRequestHandler();
            HTMLComponent htmlC = new HTMLComponent(handler);
            user = new LinkedInUser(Const.consumerKey, Const.consumerSecret);
            user.fetchNewRequestToken();

            if (user.requestToken != null) {
                authorizeUrl = "https://www.linkedin.com/uas/oauth/authorize?oauth_token="
                        + user.requestToken.getToken();
            }
            //htmlC.setPage("http://m.google.com");
            System.out.println(""+htmlC.toString());
            System.out.println(""+authorizeUrl);

            //htmlC.setPage("https://www.linkedin.com/uas/oauth/authorize?oauth_token=5a7ed20d-3a04-419d-85ea-ba99fc06ddbd");
            htmlC.setPage(authorizeUrl);
            System.out.println(authorizeUrl);
            FlowLayout flow = new FlowLayout(Component.TOP);
            form.setLayout(flow);
            form.addComponent(htmlC);



            //myMIDlet.platformRequest("http://wap.mdfactory.com");

        } catch (Exception e) {
            e.printStackTrace();
        }

        return form;
    }
}

我收到以下一组错误：

为什么会发生这种情况，请朋友帮忙！

尝试使用 http 而不是 https 打开页面。
