I can't find what I need change in web.xml <servlet> | <servlet-name>Faces Servlet</servlet-name> | <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> | <load-on-startup>1</load-on-startup> | </servlet> | | <servlet-mapping> | <servlet-name>Faces Servlet</servlet-name> | <url-pattern>*.htm</url-pattern> | </servlet-mapping> - I tried that part. But Ajax4Jsf-filter not only use on ".htm" pattern. It works for my download servlet which have url like /app/servlets/download?fileId=45&ticket=6768876 and try parse OutputSream of binary file. Can you explain how to disable Ajax4jsf-filter for my DownloadServlet only? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126002#...
