Thanks sTAN; We have tried your suggestion. We changed <mime-mapping> | <extension>xhtml</extension> | <mime-type>application/xhtml+xml</mime-type> | </mime-mapping> | into <mime-mapping> | <extension>xhtml</extension> | <mime-type>text/html</mime-type> | </mime-mapping> | After stopping und starting the server and ensuring that the browsers cache is cleared we got the same effect. So it seems that chaniging the mime type is not the correct solution. Ciao, Carsten View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4073468#...
