Problem with JPQL using JSF

I'm following a Java EE 7 book with JSF, PrimeFaces and CDI by Thiago Farias.

In my persistence.xml, following the book, I have only the definition of my datasource, as follows:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" 
                           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                           xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <persistence-unit name="GescorpPU">
    <provider>org.hibernate.ejb.HibernatePersistence</provider> 
    <properties> 
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/gescorpbd" /> 
        <property name="javax.persistence.jdbc.user" value="root" /> 
        <property name="javax.persistence.jdbc.password" value="root" /> 
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" /> 
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" /> 
        <property name="hibernate.show_sql" value="true" /> 
        <property name="hibernate.format_sql" value="true" /> 
        <property name="hibernate.hbm2ddl.auto" value="update" /> 
    </properties> 
    </persistence-unit>
</persistence>

Entity Launch:

package br.com.freela.gescorp.model;

import java.io.Serializable;
import java.math.BigDecimal;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

    @Entity
    @Table(name = "lancamento")
    public class Lancamento implements Serializable {

        private static final long serialVersionUID = 1L;

        private Long id;
        private Pessoa pessoa;
        private String descricao;
        private BigDecimal valor;
        private TipoLancamento tipo;
        private Date dataVencimento;
        private Date dataPagamento;

        // ...
    }

Method that queries the bank:

public List<Lancamento> todos(){
    TypedQuery<Lancamento> query = manager.createQuery("from Lancamento", Lancamento.class);
    return query.getResultList();
}

Exception:

 javax.faces.el.EvaluationException: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Lancamento is not mapped [from Lancamento]
