httpFileUpload plugin is not invoking

    private void handleUpload(File file, ChatRoom room, Message.Type type)
    {
        Log.warning("Uploading file: " + file.getAbsolutePath());
        String fileName = null;
        try {
            fileName = URLEncoder.encode(file.getName(), "UTF-8");
        } catch (UnsupportedEncodingException ignored) {
            // Can be safely ignored because UTF-8 is always supported
        }
        try {
            //UploadRequest request = new UploadRequest(file.getName(), file.length());
            UploadRequest request = new UploadRequest(fileName, file.length());
