java.lang.NoClassDefFoundError

Olá Tiago

É isso mesmo, está faltando o JAR da especificação da JPA, que é esse: https://mvnrepository.com/artifact/org.eclipse.persistence/javax.persistence/2.0.0

Se você está usando o maven ou similar vai ser fácil. Caso contrário vai ter de por esse JAR e talvez alguns outros que ele vai reclamar depois.

Olá Paulo,

Aparentemente deu o mesmo erro:

Tirei um print da tela https://s22.postimg.org/e4x2hx5bl/Captura_de_tela.png. Nele mostra que adicionei o jar que tu passou ao build path.

Tem alguma sugestão?

Grato!

Realmente ela está no build path. Unica possibilidade de ele nao estar achando é se o seu build path nao é o mesmo path de execucao do servidor. Por onde voce está executando seu application server? Ant? Maven? pode por o codigo?

Estou executando o application server simplesmente dando um "Start" no TomCat. É obrigatório usar o Ant ou Mavem para um projeto usando JSF e Hibernate?

Abaixo meu código: '''

package managedBean;

import javax.faces.bean.ManagedBean; import javax.persistence.EntityManager; import javax.persistence.EntityTransaction;

import dao.JPAUtil; import modelo.Automovel;

@ManagedBean //integra a view com a regra de negocio public class AutomovelBean {

private Automovel automovel = new Automovel();

public Automovel getAutomovel() { return this.automovel; }

public void setAutomovel(Automovel automovel) { this.automovel = automovel; }

public void grava(){ System.out.println("Gravando objeto modelo: " + this.getAutomovel().getModelo());

EntityManager em = JPAUtil.getEntityManager();

/EntityTransaction tx = em.getTransaction(); tx.begin(); em.persist(this.automovel); tx.commit(); em.close();/ } }

package modelo;

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

@Entity public class Automovel {

@Id @GeneratedValue(strategy=GenerationType.IDENTITY) //IDENTITY usa MySQL private Long id; private String marca; private String modelo; private Integer anoModelo; private Integer anoFabricacao; private String observacoes;

public Long getId() { return id; }

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

public String getMarca() { return this.marca; }

public void setMarca(String marca) { this.marca = marca; }

public String getModelo() { return this.modelo; }

public void setModelo(String modelo) { this.modelo = modelo; }

public Integer getAnoModelo() { return anoModelo; }

public void setAnoModelo(Integer anoModelo) { this.anoModelo = anoModelo; }

public Integer getAnoFabricacao() { return this.anoFabricacao; }

public void setAnoFabricacao(Integer anoFabricacao) { this.anoFabricacao = anoFabricacao; }

public String getObservacoes() { return this.observacoes; }

public void setObservacoes(String observacoes) { this.observacoes = observacoes; } }

package dao;

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

public class JPAUtil {

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

public static EntityManager getEntityManager(){ return emf.createEntityManager(); }}

Gratidão pela força!

Opa, não é obrigatório, mas como foi que vc adicionou a dependência? Você colocou ela diretamente na pasta WEB-INF/lib?

Adicionei uma pasta "lib" no projeto. Nessa pasta coloquei todos . jar e depois adicionei ao build path.

Essa pasta lib, está dentro da pasta WEB-INF? Isso eh obrigatório.

entra no diretorio via filesystem e manda um printscreen pra gente? dele deploiado
