Of course this is a security hole but, I did that only for example and tryed for working. I found one example but it doesn't work because some of Seam Filter or AJAX4J Filter trying buffer that stream. When I try without Seam, everything is OK. Maybe it sounds like lamers words, maybe I'm crazy but I can't found where is my problem. I use Jboss SEAM + RichFaces + EJB3. If you have that example please post it to me, and I try to understand where is my problem, and never ask about that again. Thank you! :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123963#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
