Não consegui identificar o motivo do erro abaixo em meu projeto:

Segue o código da classe JPAUtil

package br.com.caelum.livraria.dao;

import javax.enterprise.context.RequestScoped;
import javax.enterprise.inject.Disposes;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class JPAUtil {

    private static EntityManagerFactory emf = Persistence
            .createEntityManagerFactory("livraria");

    @Produces
    @RequestScoped //javax.enterprise.context.RequestScoped
    public EntityManager getEntityManager(String banco) {
        return emf.createEntityManager();
    }

    public void close(@Disposes EntityManager em) {
        em.close();
    }
}

Boa tarde!

Como está o seu arquivo persistence.xml? E, em qual pasta você colocou ele?

Rogério, segue o meu persistence.xml, que está localizado em livraria -> Java Resources -> SRC -> META-INF

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

    <persistence-unit name="livraria" transaction-type="RESOURCE_LOCAL">

        <provider>org.hibernate.ejb.HibernatePersistence</provider>

        <class>br.com.caelum.livraria.modelo.Usuario</class>
        <class>br.com.caelum.livraria.modelo.Livro</class>
        <class>br.com.caelum.livraria.modelo.Autor</class>
        <class>br.com.caelum.livraria.modelo.Venda</class>

        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/livrariadb" />
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="" />

            <property name="hibernate.hbm2ddl.auto" value="update" />

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
        </properties>
    </persistence-unit>

</persistence>

Oi Rodrigo,

O problema está no código abaixo:

 @Produces
    @RequestScoped //javax.enterprise.context.RequestScoped
    public EntityManager getEntityManager(String banco) {
        return emf.createEntityManager();
    }

Esse método não tem parâmetro. Deveria ser da seguinte forma:

 @Produces
    @RequestScoped //javax.enterprise.context.RequestScoped
    public EntityManager getEntityManager() {
        return emf.createEntityManager();
    }

Abs.
