KeyEvent and Swing

Question

Hi to all... I am facing a big problem. I want to manually dispatch KeyEvent. I can do this with AWT, i.e., create a KeyEvent Object with the desired character and call
"ta.dispatchEvent();"(where ta is java.awt.TextArea). But when I try it with the swing JTextArea it gives me a page long Exception list.

Try to run this program:
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
public class Dispat extends JFrame 
     JTextArea ta = new JTextArea("");
     JButton   jb = new JButton("Press this key to dispatch");
     int       ji = 0;
public Dispat()
     addWindowListener(new WindowAdapter()
    {     public void windowClosing(WindowEvent ev)
          {     dispose();
               System.exit(0);}});
     setBounds(1,1,600,350);
     getContentPane().setLayout(null);
     ta.setBackground(Color.pink);
     ta.setBounds(10,60,400,200);
     getContentPane().add(ta);
     jb.setBounds(10,20,200,20);
     getContentPane().add(jb);
     setVisible(true);
     jb.addActionListener(new ActionListener()
        {     public void actionPerformed(ActionEvent be) 
               char c = jb.getText().charAt(ji++);
               ta.dispatchEvent(new
                    KeyEvent(ta,KeyEvent.KEY_TYPED,0,0,KeyEvent.VK_UNDEFINED,c));
public static void main(String[] args )
     new Dispat();
