Function keys on different computers

Question

Hell-o there
I have a problem with the function keys and my application. The fact is that the application has to work without the mouse (people steals them, so there's no mouse), only with the F keys. And it works, but only on the computer where the applicaction have been developed. This is a biiiig problem for me, because the application has to work in any computer of this bloody enterprise.
They gave me JBuilder 7.0 , and the JDK it has is the 1.3.1
When I say that it doesn't work, I mean that you press an F key and nothing happens.
So, the application works on any computer that has the JBuilder installed. How can I make it work on computers without the JBuilder installed?
thank you very much! : )

Answer 1

Thank you very much for your responses, the documentation was useful, but it can't solve my problem :( , or at least I can't understand it with my english level.
The problem: on a computer with JBuilder, you press an F key and the application behaves correctly, everything's fantastic and the world is beautiful.
you try the same on another computer and nothing happens.
I've done a simple application that writes the code of the key you press on a label.
public class Pantalla extends JFrame {
this.addKeyListener(new java.awt.event.KeyAdapter() {
public void keyPressed(KeyEvent e) {
this_keyPressed(e);
void this_keyPressed(KeyEvent e) {
label.setText("El c�digo de la tecla: "+e.getKeyCode());
and the same problem. It works on a computer with JBuilder, and doesn't work on any another :(
