Topic awaiting preservation: File download

Hello together!
I have a special question on downloads:
I developed an intranet-application with JSP, which stores documents on the server and allows the user to search for them and download the documents he wants. My problem is: I offer the documents as an HTML-link in the <a href=""...>-fashion. Unfortunately with most document-types the browser immediately opens a new window showing the content as ascii, which is not nice with pictures for example. Instead I would like either opening the download&save-dialog like choosing "save target as" in the browser, or, even better, opening the document over the intranet but with the correct application (in this case, the registered graphics-program). Can you help me with this? I would be very pleased. Greetings, DreamiX.

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

DreamiX, i have used this nice PHP code:

<?php

//Put this script in the header of a file

//You can submit $Dir, $File_Name, $File_Extension by another script



$filename="filename";

$fileextension="zip";

$filedir = "c:/elias/zips/";



$fnsave = "$filename.$fileextension";

$fnread = "$filedir$filename.$fileextension";



header("Content-disposition: filename=$fnsave");

header("Content-type: application/force-download");

readfile("$fnread"); 

?>

i'm betting the "force-download" mime-type is forcing the browser to treat every file as plain/text.

A little jsp-code would be nice, since my own didn't work.
That's the download.jsp:

<%
String strFile = request.getParameter("file");
response.setContentType("application/msword");
%>
<jsp:include page='<%=strFile%>' flush="true" />

But instead of downloading the file, I just get a 2-bytes-download.jsp?!

No example code necessary any more, I wrote a servlet that works.

The MIME-Type "application/force-download" is fine, but there is one further problem: if i download the files, they are mostly correct, but in some cases the filename is replaced. The file-extension remains the original one, but the file name is replaced by "download", which is the name of my servlet. E.g. if I have a file "picture.pcx" and try to download it with my servlet the download-dialog asks for downloading "download.pcx". The file itself is the same as the original, but the name changed. How can I prevent this?
