 browse.addActionListener((evt) -> {

            Display.getInstance().openGallery(new ActionListener() {

                public void actionPerformed(ActionEvent ev) {

                    if (ev != null && ev.getSource() != null) {

                        String chemin = (String) ev.getSource();

                       

                        int index = chemin.lastIndexOf('/');

                        if (index > 0) {

                            filename = chemin.substring(index + 1);

                            System.out.println(filename);

                            try {

                                Image img = Image.createImage(chemin);

                                ImageViewer a = new ImageViewer(img);

                                content.add(a);

                                

                            } catch (IOException ex) {

                            }

                        }

                }

            }, Display.GALLERY_IMAGE);

You can use the standard multipart upload. It works like a standard HTML form with file field so should be pretty easy to process on the server side:

Maybe try to reformat your code to the following style, maybe it will help:

browse.addActionListener((evt) -> {

     ActionListener callback = e -> {

            if (e != null && e.getSource() != null) {

String filePath = (String) e.getSource();

                //System.out.println("FILEPATH TO THE IMAGE " +filePath);

               try {

Image img = Image.createImage(filePath);

ImageViewer iv = new ImageViewer(img);

add(iv);

revalidate();

} catch (IOException ex) {

}

}

    };

Display.getInstance().openGallery(callback, Display.GALLERY_IMAGE);

});
