Subject Re: File system resource for static content
Date Sun, 14 Dec 2008 17:35:12 GMT
The problem with this approach is that when you upgrade the war file  
the files will be deleted.
I believe It is better to save the files outside the web app and  
deliver them either with a symbolic link from within your war file or  
using a reader servlet.
