Alguem pode me ajudar ?

#2

Vc declarou o managedBean no faces-config.xml ?

#3

Não declarei, como eu faço isso ?

#4

O faces-config.xml fica no diretório WEB-INF e vc declara o managedbean através de tag’s.

Como vc está usando JSF 1.2 dê uma olhada nesse link http://www.algaworks.com/downloads/apostilas/algaworks-dwjsf-desenvolvimento-web-com-javaserver-faces-2a-edicao.pdf

Para JSF 2.0 nesse http://www.k19.com.br/artigos/apostila-de-jsf-2-0-disponivel-para-download-gratuitamente/
