I don't understand it...
But Myfaces libs are already included at the JBoss AS level in:
for example I import example.war in my portal.
this war file incorporates libs in "WEB-INF\libs"
I'm just wondering if Jboss portal uses its own libs or the one included the war files I import.
It's using the same classloading rules as of JBoss AS.
It all depends on your configuration, see http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoading
(For the myFaces lib for example, it will use the one in jsf-libs with the out-of-the-box configuration)
