Estou fazendo o curso Fj26 da Caelum com o Guilherme.
Tudo certo na aula, projeto rodando, etc.
Chegando em casa estou testando tudo do zero para aprender mesmo os conceitos e tudo mais.
Só que, para variar, não roda de jeito nenhum. Pararece que o eclipse não reconhece que minhas libs são do JSF 2.0. Alguém tem alguma idéia?

Obs: Estou até estranhando que até agora, com execeção do web.xml, não configurei nada de XML. E isso é bom.
