java.lang.NullPointerException at com.sun.lwuit.html.CSSEngine.applyStyleToUIElement（Unknown Source）

Question

我正在爲j2me運行帶有eclipse pulsar的S60 SDK。 我正在嘗試加載Linkedn登錄頁面。 但如果我只通過設置htmlc.setPage（）加載linkedin.com，那麼它不會顯示，那麼它只顯示linkedin名稱現在加入& ..但不顯示電子郵件& passsword文本框和登錄按鈕。下面

我的類代碼給出：

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; 
    } 
} 

我得到以下一組錯誤的：

嘗試使用http而不是https打開頁面。
