Question

我正在运行带有eclipse脉冲星的S60 SDK for j2me。我正在尝试加载Linkedn登录页面。但是，如果我只通过设置htmlc.setPage（）来加载linkedin.com，那么它就不会显示，那么它现在只显示“加入名称”和“...”但不显示电子邮件＆amp;密码短信和登录按钮。

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;
    }
}

我遇到了一系列错误：

尝试使用http而不是https打开页面。

com.sun.lwuit.html.CSSEngine.applyStyleToUIElement（未知来源）的java.lang.NullPointerException
