Events from the Timer (Swing!!) HELP

Question

I am working with a timer.. here is the code:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import javax.swing.*;
import javax.swing.Timer;
public class TestTimer implements ActionListener
Timer timer;
public TestTimer(int delay)
timer = new Timer(delay, this);
public void start() {timer.start();}
public void stop() { timer.stop();}
public void actionPerformed(ActionEvent e)
System.out.println("Action X_Y");
public static void main (String[] args)
TestTimer tt = new TestTimer(300);
tt.start();
I was expecting as the output of the program the text message "ACTION" each 300 mseconds, but I do not get any output, do you know what it is happening?
Has somebody some simple examples?
Thanks.

Thanks a lot!
I have a last problem with the Event handler and I am not sure why or how to solve it:
import java.io.* ;
import org.w3c.dom.* ;
import javax.swing.Timer;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import java.io.Serializable;
import org.w3c.dom.* ;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.*;
import java.io.* ;
import javax.swing.event.EventListenerList;
public class testHarners
public File file = null ;
public float auxFloat = 0.0f;
     public testHarners(){
file = new File("C:/temp/ProgramIndexing3.xml");
     public File getFile() {return file ;}
     public void addAuxFloat(float v) {setAuxFloat(auxFloat+v);}
     public void setAuxFloat(float f) {auxFloat = f;}
     public float getAuxFloat() {return auxFloat;}
     public static void main(String[] args)
          testHarners t = new testHarners() ;
          ParserManager p = new ParserManager(t.getFile());
          Document d = p.getDocument();
          ReaderXML reader = new ReaderXML(d);
          int delay2 = 10; //milliseconds
          ActionListener taskPerformer = new ActionListener()
          public void actionPerformed(ActionEvent evt)
                    addAuxFloat(0.01f); // ERROR
          Timer2 t2 = new Timer2(reader, t.getAuxFloat());
          new Timer(delay2,taskPerformer).start();
          while(true)
               try{  Thread.sleep( 3 );  }
               catch( InterruptedException e ){}
The error is inside actionPerformed:
EM\XMLParser\testHarners.java:95: Can't make a static reference to nonstatic variable void addAuxFloat(float) in void actionPerformed(java.awt.event.ActionEvent).
                    addAuxFloat(0.01f);
How could I solve it?
How could I get the time 0.00, 0.01, 0.02, 0.03......?
Thanks!
