[RESOLVIDO] Duvida JPA

@dnhill escreveu:

Bom dia pessoal, comecei a ler o livro da casa do código "Aplicações Java para web com JSF e JPA", porém estou com uma dificuldade.
Estou começando a aprender, então se for alguma coisa besta já peço desculpas.

Seguinte:

criei a classe Automovel:

> import javax.persistence.Entity;
> import javax.persistence.GeneratedValue;
> import javax.persistence.Id;

> @Entity
> public class Automovel {
>     @Id @GeneratedValue
>     private Long id;
>     
>     private String marca;
>     private String modelo;
>     private Integer anoFabricacao;
>     private Integer anoModelo;
>     private String observacoes;
>     
>     
>     public Long getId() {
>         return id;
>     }
>     public void setId(Long id) {
>         this.id = id;
>     }
>     public String getMarca() {
>         return marca;
>     }
>     public void setMarca(String marca) {
>         this.marca = marca;
>     }
>     public String getModelo() {
>         return modelo;
>     }
>     public void setModelo(String modelo) {
>         this.modelo = modelo;
>     }
>     public Integer getAnoFabricacao() {
>         return anoFabricacao;
>     }
>     public void setAnoFabricacao(Integer anoFabricacao) {
>         this.anoFabricacao = anoFabricacao;
>     }
>     public Integer getAnoModelo() {
>         return anoModelo;

a classe JPAUtil :

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class JPAUtil {
    
    private static final EntityManagerFactory emf = Persistence.createEntityManagerFactory("teste");
    
    public static EntityManager getEntityManager(){
        return emf.createEntityManager();
    }

}

A classe PersistidorDeAutomovel:

import javax.persistence.EntityManager;
import javax.persistence.EntityTransaction;

public class PersistidorDeAutomovel {
    public static void main(String[] args) {
        
    
        EntityManager em = JPAUtil.getEntityManager();
        
        Automovel auto = new Automovel();
        
        auto.setAnoFabricacao(2010);
        auto.setModelo("Ferrari");
        auto.setObservacoes("Nunca foi batido");
        
        EntityTransaction tx = em.getTransaction();
        tx.begin();
        em.persist(auto);
        tx.commit();
        
        em.close();
    }

}

e o persistence.xml (utilizo banco de dados oracle 11g) :

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0"
    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">
    
    <persistence-unit name="teste">
    
        <properties>
            <property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:/:@localhost:1521:xe"/>
            <property name="javax.persistence.jdbc.user" value="teste"/>
            <property name="javax.persistence.jdbc.password" value="1234"/>
            <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.driver.OracleDriver"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>    
                
        </properties>
        
    </persistence-unit>
</persistence>

E ao executar a classe PersistidorDeAutomovel, é lançada a seguinte exceção:

Se alguém puder me ajudar, agradeço desde já.
