    @WebServlet(“/ download”)

    DownloadServlet public class extends Void httpservlet

    protected doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException

    String fileLocation equals “E : video.mp4”; //Change path as specified in directory

    File in file = new File(fileLocation);

    FileInputStream fis = new FileInputStream(file);

    ServletOutputStream sos is resp.getOutputStream();


    resp.setHeader(“Content-Disposition”, “attachment; filename = ” + buffer location);

    Byte[] equals new byte[4096];

    while((, 0, 4096))! = -1 )

    sos.write(buffer, 0, 4096);

    fis.Download close();

    For a file on the server, here is a painless example. I’m assuming you’ve got the E-file home.jsp in the player you want to download. If you have a JAR or ZIP image, you can link to that file directly. So you don’t need to write to download support anyway. But if by chance there is a Java file or a JSP file, you need to create this program to load that file.

    Internet Servlet Download Related File Example

  • Index in.html
  • web.xml

    This is a servlet file, poetto which it reads the content initiated from the content and writes it to the view to send as a response.For this great purpose, we need to inform the server as a whole, so we define this content as type APPLICATION/OCTET-STREAM.

    web.xml file

    This layout file provides information about returning to the server via the servlet.
