We have some rendering issues with JBoss AS4.2.1 and all of our browsers (opera,tomcat,ie). The css is not applied correctly, so the pages do not show up as expected. With Opera and IE the pages are readable, but with Firefox it gets towards unreadability. We are using JSF, Facelets,Seam, Richfaces. Our pages worked well with jboss AS 4.0.5 (and the included Tomcat5.5). Found this qoute here: anonymous wrote : The most web servers send as type for HTML and XHTML files ?text/html?. But Tomcat 6 sends per default as type for XHTML files the type ?application/xhtml+xml?. Firefox seems to have trouble with this type Is there a configurationb option to obtain the same behaviour as with tc5.5?
