Oi Ederson,

Você pode postar o código da sua classe modelo e da sua classe DAO?

Concerteza Douglas, Obrigado pela ajuda!

Modelo Evento: package bandas.model;

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

import javax.persistence.*;

@Entity public class Evento implements Serializable {

private static final long serialVersionUID = 1L; @Id @GeneratedValue private int id; private String local; @ManyToMany private List artistas = new ArrayList();

public void relacionarArtista(Artista artista) { this.artistas.add(artista); }

public int getId() { return id; }

public void setId(int id) { this.id = id; }

public String getLocal() { return local; }

public void setLocal(String local) { this.local = local; }

public List getArtistas() { return artistas; } }

Modelo artista:

package bandas.model;

import javax.persistence.*;

@Entity public class Artista {

@Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; private String nome;

public int getId() { return id; }

public void setId(int id) { this.id = id; }

public String getNome() { return nome; }

public void setNome(String nome) { this.nome = nome; } }

DAO:

package bandas.util;

import java.util.List;

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

public class BandasDAO { private final Class classe;

public BandasDAO(Class classe) { this.classe = classe; }

public void adiciona(T t) {

EntityManager manager = new BandasJPAUtil().getManager(); manager.getTransaction().begin(); manager.persist(t); manager.getTransaction().commit(); manager.close(); }

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

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

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

public void atualiza(T t) { EntityManager manager = new BandasJPAUtil().getManager(); manager.getTransaction().begin();

manager.merge(t);

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

public List listaTodos() { EntityManager em = new BandasJPAUtil().getManager(); CriteriaQuery query = em.getCriteriaBuilder().createQuery(classe); query.select(query.from(classe));

List lista = em.createQuery(query).getResultList();

em.close(); return lista; }

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

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

return (int) result; }

public List listaTodosPaginada(int firstResult, int maxResults) { EntityManager em = new BandasJPAUtil().getManager(); CriteriaQuery query = em.getCriteriaBuilder().createQuery(classe); query.select(query.from(classe));

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

em.close(); return lista; }

}

O Bean do Artista está funcionando normalmente. Apenas o Evento que não. Se poder ajudar agradeço. Valeu!!!

Bean Evento: package bandas.bean;

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

import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; import javax.swing.JOptionPane;

import bandas.model.Artista; import bandas.model.Evento; import bandas.util.BandasDAO;

@ManagedBean @ViewScoped public class EventoBean implements Serializable {

private static final long serialVersionUID = 1L; private Evento evento = new Evento(); private int artistaId;

public Evento getEvento() { return this.evento; }

public List getArtistas() { return new BandasDAO(Artista.class).listaTodos(); }

public void relacionarArtista() {

try { Artista artista = new BandasDAO(Artista.class) .buscaPorId(this.artistaId); this.evento.relacionarArtista(artista); testeBotao(); } catch (Exception e) { throw new RuntimeException("Não criado relacionamento com o artista"); } }

public void testeBotao() { JOptionPane.showMessageDialog(null, "Botão Pressionado"); }

public void publicarEvento() {

System.out.println(" >> " + evento.getLocal()); if (evento.getArtistas().isEmpty()) { throw new RuntimeException("Artistas não selecionados"); }

try { new BandasDAO(Evento.class).adiciona(this.evento); this.evento = new Evento(); } catch (Exception e) { throw new RuntimeException("Evento Não Publicado"); } }

public int getArtistaId() { return artistaId; }

public void setArtistaId(int artistaId) { this.artistaId = artistaId; } }

Ederson, tenta adicionar junto a anotação, o strategy na classe Evento

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;

Ederson, bom, tenta apagar as tabelas para que sejam criadas novamente, mas agora com o strategy setado ou tente diretamente utilizar esse sql, assumindo que você está usando o mysql.

insert into mysqldb.hibernate_sequence(next_val) values(0)
