        response.setContentType((context.getMimeType(fileName) != null) ? context.getMimeType(fileName) : "application/pdf");
        response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName);
        InputStream inputStream = context.getResourceAsStream("/" + fileName);
        byte[] bytes = new byte[1024];
       
        while((inputStream != null) && ((lenght = inputStream.read(bytes)) != -1)) {
            outputStream.write(bytes, 0, lenght);
        }
        outputStream.flush();
