eclipse (java animation issues)

im having lots of problems in running this simple animation.
the program just shows 1 frame, which is the last frame(i believe), on a windows computer, i can easily run this with eclipse, but on a mac, i've got always the same problems! HELP!

class chute extends JFrame implements MouseMotionListener{
public JLabel x,y;
public JPanel p1;
public static void main(String[]args){
JFrame janela=new chute();
janela.show();
}
chute(){
setTitle("chute");
getContentPane().setLayout(new BorderLayout());
setSize(300,300);
setLocation(90,90);
p1=new JPanel();
p1.setLayout(new BorderLayout());
x=new JLabel("x");
y=new JLabel("y");
p1.add(x,"North");
p1.add(y,"South");
getContentPane().addMouseMotionListener(this);
getContentPane().add(p1,"South");
