Boa tarde Priscila, esse erro ocorre por falta da taglib jstl, pode verificar se esses dois jars estão no classpath?

jsp-api-2.0.jar
jstl-1.2.jar

Espero ter ajudaro. Abraços

Olá Priscila tudo bem?

Tem como mandar o xhtml da página que você está acessando e ocorre esse erro e seu ManagedBean referente a essa página.

Os jars que você inseriu estão no seu buildpath?

Depois de copiar para a pasta lib voce clicou com o botao direito > add to buildPath?

porque geralmente java.lang.ClassNotFoundException ocorre por problemas no jar.

Olá Luiz fiz isso sim, elas estão na pasta JRE System Library, será que é nessa pasta mesmo?

Alisson segue meu DAO

package br.com.caelum.livraria.dao;

import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.criteria.CriteriaQuery;

public class DAO<T> {

    private final Class<T> classe;

    public DAO(Class<T> classe) {
        this.classe = classe;
    }

    public void adiciona(T t) {

        // consegue a entity manager
        EntityManager em = new JPAUtil().getEntityManager();

        // abre transacao
        em.getTransaction().begin();

        // persiste o objeto
        em.persist(t);

        // commita a transacao
        em.getTransaction().commit();

        // fecha a entity manager
        em.close();
    }

    public void remove(T t) {
        EntityManager em = new JPAUtil().getEntityManager();
        em.getTransaction().begin();

        em.remove(em.merge(t));

        em.getTransaction().commit();
        em.close();
    }

    public void atualiza(T t) {
        EntityManager em = new JPAUtil().getEntityManager();
        em.getTransaction().begin();

        em.merge(t);

        em.getTransaction().commit();
        em.close();
    }

    public List<T> listaTodos() {
        EntityManager em = new JPAUtil().getEntityManager();
        CriteriaQuery<T> query = em.getCriteriaBuilder().createQuery(classe);
        query.select(query.from(classe));

        List<T> lista = em.createQuery(query).getResultList();

        em.close();
        return lista;
    }

    public T buscaPorId(Integer id) {
        EntityManager em = new JPAUtil().getEntityManager();
        T instancia = em.find(classe, id);
        em.close();
        return instancia;
    }

    public int contaTodos() {
        EntityManager em = new JPAUtil().getEntityManager();
        long result = (Long) em.createQuery("select count(n) from livro n")
                .getSingleResult();
        em.close();

        return (int) result;
    }

    public List<T> listaTodosPaginada(int firstResult, int maxResults) {
        EntityManager em = new JPAUtil().getEntityManager();
        CriteriaQuery<T> query = em.getCriteriaBuilder().createQuery(classe);
        query.select(query.from(classe));

        List<T> lista = em.createQuery(query).setFirstResult(firstResult)
                .setMaxResults(maxResults).getResultList();

        em.close();
        return lista;
    }

}

Obrigada pela ajuda!

Priscila, você precisa adicionar no diretório WEB-INF/lib da tua aplicação essas 3 bibliotecas:

jsf-impl.jar Disponível em: http://central.maven.org/maven2/com/sun/faces/jsf-impl/2.2.14/jsf-impl-2.2.14.jar

jsf-api.jar Disponível em: http://central.maven.org/maven2/com/sun/faces/jsf-api/2.2.14/jsf-api-2.2.14.jar

jstl.jar Disponível em: http://central.maven.org/maven2/javax/servlet/jstl/1.2/jstl-1.2.jar

Coloca elas lá, reinicia o servidor e testa de novo...
