For those seeking to add IE9 compatiblity in the WebAccess, without doing it on all clients :

Edit /var/opt/novell/tomcat5/webapps/gw/WEB-INF/classes/templates/webacc/css/head.inc

Add those lines to the end of the file :
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" >
<meta http-equiv="X-UA-Compatible" content="IE=7.5" > <!-- IE7 mode -->

(not sure the first is needed)

Restart tomcat5, and you are done : rcnovell-tomcat5 restart
