E aí Rodrigo! Sou eu quem estava mandando aquelas dúvidas pra vc!
Segue o código da minha página contato.jsp:
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

Eu procurei por esse erro no google mas não encontrei uma resposta satisfatória… vou colocar tb meu managed Bean :
public class ContatoManaged {
public ContatoManaged() {}
private Contato contato = new Contato();
private GerenciaContatos gerenciaContatosManager;
public void setGerenciaContatosManager(GerenciaContatos gerenciaContatosManager) {
this.gerenciaContatosManager = gerenciaContatosManager;
}
public GerenciaContatos getGerenciaContatosManager() {
return gerenciaContatosManager;
}
public List getContatos(){
return this.gerenciaContatosManager.getContatos();
}
public Contato getContato() {
return contato;
}
public void setContato(Contato contato) {
this.contato = contato;
}
}
Meu faces-config.xml está dessa forma:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

E a minha classe que contém o método pra salvar o contato:
public class GerenciaContatos {
private ContatoDAO dao;
public void setContatoDao(ContatoDAO dao) {
this.dao = dao;
}
public List getContatos(){
return dao.getContatos();
}
public Contato salvarContato (Contato objContato){
dao.salvarContato(objContato);
return objContato;
}
public void removerContato (Contato objContato){
dao.removerContato(objContato);
}
public Contato getContato(Long contatoId){
return dao.getContato(contatoId);
}
}
Esse erro tb acontece em um projeto de exemplo que eu peguei (hibernate + spring + jsf tb…)… logo quando eu entro na página, aparece a mesma mensagem no console do Tomcat… nos dois eu estou usando o MySQL 5…
Muito Obrigado!
