NetBeans教程：創建圖形客戶端Twitter並

Question

我在練上創建在以下鏈接找到的Twitter圖形客戶端的NetBeans教程：http://netbeans.org/kb/docs/websvc/twitter-swing.html我使用NetBeans 7.1

下面

是教程的代碼片段

public class TwitterFrame extends javax.swing.JFrame { 

     /** 
     * Creates new form TwitterFrame 
     */ 
     public TwitterFrame() { 
      initComponents(); 

      try { 
      initUserInfo(); 
     } catch (IOException ex) { 
      Logger.getLogger(TwitterFrame.class.getName()).log(Level.SEVERE, null, ex); 
     } 
     } 



    private void initUserInfo() throws MalformedURLException, IOException { 

      //Create an instance of the internal service class 
     client = new Twitter_OAuth_user_timeline__format_JerseyClient("xml"); 


     //Log in, get tokens, and append the tokens to the consumer and secret 
     //keys 
     client.login(); 
     client.initOAuth(); 

     //Call getUserTimeline, get a list of statuses, pass the most recent 
     //status as a StatusType object, and display the text of that object 
     //in the JTextField 
     Statuses statuses = client.getUserTimeline(Statuses.class, null, null, null, "1"); 
      twitter.twitteroauth.twitterresponse.StatusType st = statuses.getStatus().get(0); 
     jTextField1.setText(st.getText().trim()); 

     //Get a UserType object from the StatusType object, get the URL of that 
     //user's icon, and display that icon in the JLabel 
     UserType user = st.getUser(); 
     String iconSrc = user.getProfileImageUrl(); 
     URL iconUrl = new URL(iconSrc); 
     ImageIcon icon = new ImageIcon(iconUrl, user.getScreenName()); 
     jLabel1.setIcon(icon); 

    } 


public static void main(String args[]) { 
     /* 
     * Set the Nimbus look and feel 
     */ 
     //<editor-fold defaultstate="collapsed" desc=" Look and feel setting code (optional) "> 
     /* 
     * If Nimbus (introduced in Java SE 6) is not available, stay with the 
     * default look and feel. For details see 
     * http://download.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html 
     */ 
     try { 
      for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) { 
       if ("Nimbus".equals(info.getName())) { 
        javax.swing.UIManager.setLookAndFeel(info.getClassName()); 
        break; 
       } 
      } 
     } catch (ClassNotFoundException ex) { 
      java.util.logging.Logger.getLogger(TwitterFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); 
     } catch (InstantiationException ex) { 
      java.util.logging.Logger.getLogger(TwitterFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); 
     } catch (IllegalAccessException ex) { 
      java.util.logging.Logger.getLogger(TwitterFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); 
     } catch (javax.swing.UnsupportedLookAndFeelException ex) { 
      java.util.logging.Logger.getLogger(TwitterFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); 
     } 
     //</editor-fold> 

     /* 
     * Create and display the form 
     */ 
     java.awt.EventQueue.invokeLater(new Runnable() { 

      public void run() { 
       new TwitterFrame().setVisible(true); 
      } 
     }); 
    } 

但螞蟻時間我在netbeans上運行代碼我得到以下錯誤。

任何人有關於如何運行教程的建議。 謝謝。

Answer 1

我猜URL自從Netbeans教程寫完以後，現在是https://api.twitter.com/oauth/request_token根據Twitter documentation。

這個例外表明你打電話給：http://twitter.com/oauth/request_token。

你錯過了api.
