Thank you for your reply. Our application hold the different document in html or pdf form in database. So after user request I only copy/replace the existing file in the deploy\..\docs\ directory and want to show to the user everytime only the actuall file - is is very importent. I think you response.set header is almost the same as mine. Do you have another decisions? Thank you. By View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083312#...
