Swing/AWT/SWT :: Move Focus From Specific Jcombobox To Specific Jtextarea?

How do I move focus from a jcombobox to a specific component say a jtextarea.

My attempt below seems to be moving to a random component not the desired jtextarea.

takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});

I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.

dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});
