WELD-001408: Unsatisfied dependencies for type LivroDao with qualifiers @Default

Talvez não seja a causa do erro, mas tem algo, aparentemente, errado no seu projeto. Você está dizendo que está usando JTA, mas você está usando " ". Acredito que o mais correto seria:

Outra coisa, você colocou o arquivo beans.xml dentro do WEB-INF?

Fiz as devidas correções necessárias mas mesmo assim ainda continua os erros apresentados acima

Fala aí Anderson blz?

Pode mandar seu produtor de GenericDao?

Se você configurou o datasource pelo servidor de aplicação, deve usar somente o @PersistenceContext ao invés do @Inject para injetar o EntityManager, e não deve produzi-lo.

Outra coisa porque os DAO's estão com escopo de aplicação ?

Olá Fernando! Tudo bem? Eu retirei @Inject do EntityManager e coloquei a anotação @PersistenceContext(unitName = "livraria") no EntityManager conforme o a classe GenericDao abaixo. Agora aparece um ponto de exclamação em amarelo ao lado dos @Inject (daos específicos injetados) nas classes do beans. No Markers do eclipse apresentado um warning do tipo: No bean is eligible for injection to the injection point [JSR-346 §5.2.2]. Neste modelo apresenta um erro do tipo: Caused by: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'autorBean' resolved to null. Qual seria então a correção pra isso?

package br.project.livraria.dao;

import java.io.Serializable;
import java.util.List;

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

public class GenericDao<T, K> implements Serializable {
    private static final long serialVersionUID = 1L;
    private final Class<T> classe;

    @PersistenceContext(unitName = "livraria")
    private EntityManager em;

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

    public void adiciona(T t) {
        em.persist(t);
    }

    public void remove(T t) {
        em.remove(em.merge(t));
    }

    public void atualiza(T t) {
        em.merge(t);
    }

    public List<T> listaTodos() {

        CriteriaQuery<T> query = em.getCriteriaBuilder().createQuery(classe);
        query.select(query.from(classe));

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

        return lista;
    }

    public T buscaPorId(K id) {

        T instancia = em.find(classe, id);

        return instancia;
    }

    public int contaTodos() {

        long result = (Long) em.createQuery("select count(n) from livro n").getSingleResult();

        return (int) result;
    }

    public List<T> listaTodosPaginada(int firstResult, int maxResults) {

        CriteriaQuery<T> query = em.getCriteriaBuilder().createQuery(classe);
        query.select(query.from(classe));

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

        return lista;
    }

    public EntityManager getEm() {
        return em;
    }

}

Agora tem-se esse erro:

Fala aí Anderson, tudo bem?

Então para eu poder te ajudar preciso da classe que produz o seu GenericDao e não da classe que define ele.

Pode me enviar o seu produtor de GenericDao?

Ok Fernando, vamos lá:

package br.project.livraria.dao;

    public LivroDao(EntityManager em, Class<Livro> classe) {
        super(classe);
        // TODO Auto-generated constructor stub
    }
}

package br.project.livraria.dao;
