you need to give the links(href) to the user on browser.The href will contain the path of your file on the server.Since browser does not understand other than html, when it tries to access the specified file(given by your href) it will show a prompt having option for save and open. When you click save ,file will be downloaded to the client.
If the files are within your webapp and can be reached from the browser, just provide links. If you need to provide access to files that reside somewhere else on the filesystem or network, you'll need to:
Set the Content-Type header
Set the Content-Disposition header
Stream the file to the client with a ServletOutputStrem
Look at SimpleStream on http://simple.souther.us. It streams files from within the app using getResourceAsStream. You would need to change it to use a FileReader if you want to send files that live outside of the webapp. [ May 04, 2005: Message edited by: Ben Souther ]
