Java Applet Upload

Bonjour,

Quelqu'un a déjà fait un applet pour uploader des fichiers? Le mien semble lire le fichier à uploader mais il ne l'écrit pas sur le serveur. C'est un code que j'ai trouvé sur internet et que j'ai modifié. J'ai créé le certificat alors ce n'est pas un problème de sécurité. Il n'y a aucune erreur affichée dans la console java. Je vous donne un bout de code (un grand bout) de la classe qui upload.

public uploadWindow (String filenameVarName, String uploadPath) {
// Change le titre de la fenêtre (doit être la première ligne du constructeur)
super("Transfert");

getURL(uploadPath);

// CREATE THE WINDOW INTERFACE
// Create the frame (called frame but is a detached window);
c = getContentPane();
c.setLayout(new BorderLayout());

c.add(m_top, BorderLayout.NORTH);
c.add(m_center, BorderLayout.CENTER);
c.add(m_bottom, BorderLayout.SOUTH);

// Add all the cancel button
m_cancelButton = new JButton("Cancel");
m_bottom.add(m_cancelButton, BorderLayout.CENTER);
m_cancelButton.addActionListener(this);

// Add the status label to it
m_status = new JLabel("Initialisation...");
m_top.add(m_status, BorderLayout.WEST);

// Add the transfer rate string
m_rateLabel = new JLabel("Transfert du fichier " + fd.getFile() + ": 0 Bps, 0%, 0 / 0 bytes");
m_top.add(m_rateLabel, BorderLayout.EAST);

m_bar = new progress();
m_center.add(m_bar);

// Get the progress indicator bounds
progressRect = m_center.getBounds();

// Show the frame
int width = 750;
int height = 110;
setSize(width, height);
setVisible(true);
show();
addWindowListener(this);

uploadButton.setEnabled(false);
choisir.setEnabled(false);

afficher = new Affichage();
afficher.start();
m_thread = Thread.currentThread();


// Added getDirectory() so it can upload from anywhere
String selectedFileName = fd.getDirectory() + fd.getFile();

if (selectedFileName == null) {
dispose();
return;
}

// Loads the file in memory for uploading
File binaryFile = new File(selectedFileName);
long binaryFileLength = binaryFile.length();

// Connect the socket to the selected ip and port
m_status.setText("Recherche de l'hôte " + serverNameUrl + " ...") ;

// Try resolving the server name (needs NET access in java security flags)
try {
addr = InetAddress.getByName(serverNameUrl);
