Thanks for your replays, though I managed to fix (kinda) this problem my myself. Well I thought that if JBoss AS 4.2.2 cames with embeded JSF library, I won`t have to include any implementations into my EAR. I was wrong. When there were no jsf implementation included the "no aplication context active" was thrown. But when I`ve added Facelets (1.1.11) - aplication deployed.
