    protected void service(HttpServletRequest req, HttpServletResponse res) 
                throws ServletException, IOException {
        String path = req.getRequestURI().split("/file")[1];

        Path source = Paths.get(FileSaver.SERVER_PATH + "/" + path);
        FileNameMap fileNameMap = URLConnection.getFileNameMap();
        String contentType = fileNameMap.getContentTypeFor("file:"+source);

        res.reset();
        res.setContentType(contentType);
        //linha32
        res.setHeader("Content-Length", String.valueOf(Files.size(source)));

        res.setHeader("Content-Disposition", 
                "filename=\""+source.getFileName().toString() + "\"");
        FileSaver.transfer(source, res.getOutputStream());
    }

}
