            File fileToDownload = new File(filePathToBeServed+fileName);

            InputStream inputStream = new FileInputStream(fileToDownload);
            response.setContentType("application/force-download");
            response.setHeader("Content-Disposition", "attachment; filename="+fileName); 
            IOUtils.copy(inputStream, response.getOutputStream());
            response.flushBuffer();
            inputStream.close();
        } catch (Exception exception){
            System.out.println(exception.getMessage());
        }
