File download

How do I implement a file download in Struts?

Put a link to the file that you want the users to download.

Hi
I dont think its a good idea to place that document as a link ...becuase with that u wont be able to control the Header variables(like dispaly name of the file to be downloaded) and also u cant handle exceptions like filenotfound..........and even giving in a link makes the user to know the url(if u not using frames)
Hence i would advise u to call a servlet(action class) and there inside that redirect it to the url where the document is present .(THus url wont be visible and u can handle filenotfound exception ) and also u can set the response header variables like
response.setContentType("application/x-download");(This forces to open that windows save dialog box)
response.setHeader("Content-Disposition", "attachment; filename=" + docName);( this will cahnge the display name of the file while showing the dialog box)

I think they would still know the url if you're using frames - View Source.
Good suggestions, Sreenath.
