Deplyoing very simple JARs, like: https://issues.apache.org/jira/secure/attachment/12435313/MyFaces_Test.jar

Sure, when you extend the "old" Facelets classes, you have to have it deployed as well (and there is some parameter to disable Facelets2) -Matthias -- Matthias Wessendorf blog: http://matthiaswessendorf.wordpress.com/ sessions: http://www.slideshare.net/mwessendorf twitter: http://twitter.com/mwessendorf
