怎么输出带有超链接的字符串？

JEditorPane支持简单的网页，它的子类JTextPane能像QQ一样加入JLabel、JButton等组件，可以设置文字显示不同的字体、颜色等。

这个是怎么触发超链接事件吧..但我现在要输出带有超链接的文字 ,难道就要按html格式输出 ?但我写的是一个简单聊天程序..我想双方发送的文字带上超链接 ..这怎么做

以前写的个JTextPane例子，可以参考下：import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.text.*;
import java.io.*;public class Test {
  JFrame frame;
  JTextPane textPane;
  File file;
  Icon image;  public Test(){
    frame = new JFrame("JTextPane");
    textPane = new JTextPane();
    file = new File("./classes/test/icon.gif");
    image = new ImageIcon(file.getAbsoluteFile().toString());
  }  public void insert(String str, AttributeSet attrSet) {
    Document doc = textPane.getDocument();
    str ="\n" + str ;
    try {
      doc.insertString(doc.getLength(), str, attrSet);
    }
    catch (BadLocationException e) {
      System.out.println("BadLocationException: " + e);
    }
  }  public void setDocs(String str,Color col,boolean bold,int fontSize) {
    SimpleAttributeSet attrSet = new SimpleAttributeSet();
    StyleConstants.setForeground(attrSet, col);
    //颜色
    if(bold==true){
      StyleConstants.setBold(attrSet, true);
    }//字体类型
    StyleConstants.setFontSize(attrSet, fontSize);
    //字体大小
    insert(str, attrSet);
  }  public void gui() {
    textPane.insertIcon(image);
    setDocs("第一行的文字",Color.red,false,20);
    setDocs("第二行的文字",Color.BLACK,true,25);
    setDocs("第三行的文字",Color.BLUE,false,20);
    frame.getContentPane().add(textPane, BorderLayout.CENTER);
    frame.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }});
    frame.setSize(200,300);
    frame.setVisible(true);
  }
  public static void main(String[] args) {
    Test test = new Test();
    test.gui();
  }
}
