Hello Dave, I guess the link you sent is pointing to a similar way of doing it as I did. This is my reference: http://sheetalshundori.blogspot.com/2008/02/struts2-dynamic-file-download.html
The reason why I am doing like this is because I don't want it to be possible to download the file without entering some kind of "ordernumber". I.e. the file must be protected. The reason why I chosed this solution is simply because that is the solution I found while googleing. Is there perhaps a better way of doing this?
