Key events on the glasspane

Question

I'm trying to develop a glasspane that captures the key events as well as the mouse events.. In this example, the mouse events happen exactly the way I want them to, but I cannot for the life of me get a key event to register.. I've tried capturing keyTyped(), keyPressed(), and keyReleased() to no avail.. Dukes to whoever shows me the light,
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class BCInv
    extends JFrame {
  JScrollPane jScrollPane1 = new JScrollPane();
  JTextArea jTextArea1 = new JTextArea();
  JScrollPane jScrollPane2 = new JScrollPane();
  JTable jTable1 = new JTable();
  JButton jButton1 = new JButton();
  public BCInv() {
    jbInit();
    setVisible(true);
    getGlassPane().setVisible(true);
    //here I'm adding both listeners in the same manner
    getGlassPane().addMouseListener(new BCInv_mouseAdapter());
    getGlassPane().addKeyListener(new BCInv_keyAdapter());
  public void jbInit() {
    setSize(new Dimension(611, 423));
    getContentPane().setLayout(null);
    jScrollPane1.setBounds(new Rectangle(9, 275, 574, 110));
    jTextArea1.setText("jTextArea1");
    jScrollPane2.setBounds(new Rectangle(10, 13, 573, 175));
    jButton1.setBounds(new Rectangle(196, 217, 89, 42));
    jButton1.setText("jButton1");
    this.getContentPane().add(jScrollPane1, null);
    this.getContentPane().add(jScrollPane2, null);
    this.getContentPane().add(jButton1, null);
    jScrollPane2.getViewport().add(jTable1, null);
    jScrollPane1.getViewport().add(jTextArea1, null);
  public static void main(String[] args) {
    BCInv BC = new BCInv();
  //this key stuff here never executes..
  void BCkey(KeyEvent e) {
    System.out.println("A key was typed: '"+e.getKeyChar()+"' = "+e.getKeyCode());
  class BCInv_keyAdapter extends java.awt.event.KeyAdapter {
    BCInv_keyAdapter() {}
    public void keyTyped(KeyEvent e) {
      BCkey(e);
  //All this mouse stuff works great..
  void BCmouseClicked(MouseEvent e) {
    System.out.println("click");
    Point glassPanePoint = e.getPoint();
    boolean inButton = false;
    boolean inMenuBar = false;
    Component component = null;
    Container container = getContentPane();
    Point containerPoint = SwingUtilities.convertPoint(
        getGlassPane(),
        glassPanePoint,
        getContentPane());
    component = SwingUtilities.getDeepestComponentAt(
        container,
        containerPoint.x,
        containerPoint.y);
    if (component == null) {
      return;
    System.out.println("underlying component="+component.toString());
  class BCInv_mouseAdapter
      extends java.awt.event.MouseAdapter {
    BCInv_mouseAdapter() {}
    public void mouseClicked(MouseEvent e) {
      BCmouseClicked(e);
}
