Re: How to download file in Servlet?

[Henry Reardon]

I used the following code to do something very similar to what you are
trying to do. 'fZip' is a File reference to the file I want to download. It
will normally download automatically but, if that fails, it creates a
download link that the user can click manually. This code works very well
for me.
/* Get the name of the zip file without any of the path information. */
  String strZipName = fZip.getName();
  out.println("<META http-equiv=\"Refresh\" content=\"2; URL=" +
request.getContextPath() + "/" + strZipName + "\">");
  out.println("</head>");
  out.println("<h1>Download Zip File</h1>");
  out.println("<p>In a few seconds, your browser should pop up a 'Save As'
dialog. If it does not, <a href=\"" + request.getContextPath() + "/" +
strZipName + "\">click here</a>.</p>");
  out.println("</body>");
  out.println("</html>");
Good luck,

Rhino
