It is better to put this code into servlet. If servlet is used, you need a html form, some setting in web.xml and a servlet. You are a beginner, download is not an easy function.

Redxxiv : Some people do not want the file can be downloaded by a hyperlink because they want the download available to the login users. If you use a hyperlink download, people can download it without login.
