How can I do double click on JTree of my laptop to transfer files to server using FTP4j thank you 

public void mouseClicked(MouseEvent e) {
    String s = arbre.getLastSelectedPathComponent().toString();
    File file = new File(s);
    if(file.isFile()) {
        System.out.println("c'est un fichier");
        if(e.getClickCount()==2){
      client.upload(file);
      }
}

Using getClickCount(), you can detect double clicks in a MouseListener, as shown here. Start the transfer in your implementation of the doInBackground() method of SwingWorker. Use setProgress() to notify a listening progress indicator as the transfer proceeds, as shown here. You can show progress in a TreeCellRenderer, illustrated here. Beacuase nodes share the same renderer, you'll need to store progress elsewhere , typically in your implementation of TreeModel.

Addendum: A very simple way to display a JTree of files is shown here.

    Essen unfortunely there is no an easy way. You have to learn by your own, not "do the job for me". Take a look to [tutorials](http://docs.oracle.com/javase/tutorial/uiswing/) – nachokk Mar 12 '14 at 01:09
