这两个java编的浏览器老报错，改不来了！！

第一个：
import java.io.IOException;
import java.net.URL;
import java.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.swing.event.*;

public class WebBrowser extends JFrame{
JPanel contentPane;
BorderLayout borderLayoutAll =new BorderLayout();
JLabel jLabelPrompt =new JLable();
JPanel jPanelMain=new JPanel();
BorderLayout borderLayoutMain =new BorderLayout();
JTextField textFieldURL =new JTextField();
JEditorPane jEditorPane =new JEditorPane();

public WebBrowser(){
try{
Init();
} catch (Exception e){
e.printStackTrace();
}
}
private void Init() throws Exception{
contentPane=(JPanel) getContentPane();
contentPane.setLayout (borderLayoutAll);
jPaneMain.setLayout(borderLayoutMain);
jLablePrompt.setText("请输入地址");
textFieldURL.setText("");
textFieldURL.addActionListener(new java.awt.eve

一个模拟的IE浏览器?还不错嘛,不过功能还可以改进
