ok, i change and begin to use JSF RI, but then emerge 2 questions: 1:- An old application that uses myfaces can't be deployed in JBoss 4.2.x? 2:- How can i use Tomakwou, Sambox, Trinidad and other component libraries, i have to include them in my WEB-INF/lib, those component libraries are include in JBoss libraries? I have to configurate them in web.xml like before? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4101317#...
