Bonjour ,
Mon objectif est de télécharger une image et de la copie dans une repertoire precise mais cela ne fonctionne pas , l'image apparait dans le jlabel mais elle n'existe pas dans le repertoire signature 

/** upload image***/
    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

   
    try {
        JFileChooser chooser = new JFileChooser();
        chooser.showOpenDialog(null);
        File f = chooser.getSelectedFile();
        lb1_Image.setIcon(new ImageIcon(f.toString()));

        
      
        
         String cli=jTextField1.getText();
        conca=Agence+"_"+cli;
        jTextField4.setText(conca);
String newPath ="C:\\signature";
System.out.println(newPath);
File directory = new File(newPath);

if(!directory.exists())         
{
    directory.mkdirs();
}
System.out.println(directory);
File sourceFile = null;
File destinationFile = null;

        sourceFile = new File(filename);
        System.out.println(sourceFile);
         destinationFile = new File(newPath+"/newImage");
        System.out.println(destinationFile);
Files.copy(sourceFile.toPath(),destinationFile.toPath());

      
    } catch (IOException ex) {
        Logger.getLogger(Menu.class.getName()).log(Level.SEVERE, null, ex);
    }
    }

Bonjour,

Tu as deux erreurs dans tes logs, il faudrait regarder le code qui correspond aux lignes indiquées.
  • signature.Menu.jButton1ActionPerformed(Menu.java:329)
  • signature.Menu.jButton2ActionPerformed(Menu.java:423)

Ça devrait plutôt être E:\signature, il manque le \
