Serialize in XML

Question

Hello,
I have a question.
Why this does't works ?
I have a class
import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.beans.XMLEncoder;
public class Voiture {
    private String marque = new String();
    private String couleur = new String();
    private int nbPortes = 4;
    private long kmParcourus = 0;
    private double uneValeurDouble = 0;
    public Voiture(String marque, String couleur, int nbPortes, long kmParcourus, double uneValeurDouble) {
        this.marque = marque;
        this.couleur = couleur;
        this.nbPortes = nbPortes;
        this.kmParcourus = kmParcourus;
        this.uneValeurDouble = uneValeurDouble;
    public String getMarque() {
        return marque;
    public void setMarque(String marque) {
        this.marque = marque;
    public String getCouleur() {
        return couleur;
    public void setCouleur(String couleur) {
        this.couleur = couleur;
    public int getNbPortes() {
        return nbPortes;
    public void setNbPortes(int nbPortes) {
        this.nbPortes = nbPortes;
    public long getKmParcourus() {
        return kmParcourus;
    public void setKmParcourus(long kmParcourus) {
        this.kmParcourus = kmParcourus;
    public double getUneValeurDouble() {
        return uneValeurDouble;
    public void setUneValeurDouble(double uneValeurDouble) {
        this.uneValeurDouble = uneValeurDouble;
    public static void main(String argv[]) {
        Voiture uneVoiture = new Voiture("Une marque", "Bleue",5,1000,5.2);
        try {
            FileOutputStream filOut = new FileOutputStream( "uneVoiture.xml" );
            XMLEncoder encoder = new XMLEncoder( filOut );
            encoder.writeObject(uneVoiture);
            encoder.close();
            filOut.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();  //To change body of catch statement use Options | File Templates.
        } catch (IOException e) {
            e.printStackTrace();  //To change body of catch statement use Options | File Templates.
}And when I run it, the xml file is
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.2_02" class="java.beans.XMLDecoder">
</java> Why the serailization doesn't works ???
Please help me
Thanks
