Olá Pessoal, estou tentando utilizar o hibernate no netbenas, sou iniciante, vejam o código:

public class Aluno {

// Atributos da Classe

private int RA;

private String nome;

private String email;

private String telefone;

private String celular;

private String curso;

private String serie;

private String campus;

/** Creates a new instance of Aluno */
public Aluno() {
}

// Métodos Set e Get
public int getRA(){
    return RA;
}

public void setRA(int ra){
    this.RA = RA;
}

public String getNome(){
    return nome;
}

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

public String getEmail(){
    return email;
}

public void setEmail(String email){
    this.email = email;
}

public String getTelefone(){
    return telefone;
}

public void setTelefone(String telefone){
    this.telefone = telefone;
}

public String getCelular(){
    return celular;
}

public void setCelular(String celular){
    this.celular = celular;
}

public String getCurso(){
    return curso;
}

public void setCurso(String curso){
    this.curso = curso;
}

public String getSerie(){
    return serie;
}

public void setSerie(String serie){
    this.serie = serie;
}

public String getCampus(){
    return campus;
}

public void setCampus(String campus){
    this.campus = campus;
}

}

Kra fiz o q vc falou, porém ele fala que não consegue achar os arquivos hibernate.properties e Aluno,hbm.xml, eles estão na mesma pasta do projeto que estou fazendo, como não tava dando certo fiz isto:

import org.hibernate.<em>;

import org.hibernate.cfg.Configuration;

import java.util.</em>;

/**

public class AlunoDAO {

// Atributos da Classe

private org.hibernate.SessionFactory factory;

public AlunoDAO() throws HibernateException{

String driver   = “org.postgresql.Driver”;

String url      = “jdbc/:postgresql/://localhost/lagg_aluno”;

String user     = “Paulo”;

String senha    = “”;

String min_size = “5”;

String max_size = “0”;

String time_out = “1800”;

String max_st   = “50”;

String dialect  = “org.hibernate.dialect.PostgreSQLDialect”;

Properties propriedades = new Properties();

propriedades.setProperty(“hibernate.connection.driver”, driver);

propriedades.setProperty(“hibernate.c3p0.timeout”, time_out);

propriedades.setProperty(“hibernate.c3p0.max_statements”, max_st);

propriedades.setProperty(“hibernate.dialect”, dialect);

Configuration cfg = new Configuration();

cfg.setProperties(propriedades);

cfg.addClass(Aluno.class);

factory = cfg.buildSessionFactory();

    }

    public void Insert(Aluno aluno)throws Exception{

Session session = factory.openSession();

session.save(aluno);

session.flush();

session.close();

}

    public java.util.List getList(String condicao) throws Exception{

session.flush();

session.close();

return(alunos);

}

    public Aluno retrieve(String pk)throws Exception{

Session session = factory.openSession();

Aluno aluno = (Aluno)session.load(Aluno.class,pk);

session.flush();

session.close();

return aluno;

}

    public void delete(Aluno aluno) throws Exception{

Session session = factory.openSession();

session.delete(aluno);

session.flush();

Antes de mais nada, quando for posta código, coloque-o entre as tags [ code]seucodigo[ /code], assim ele fica endentado.

Como você declarou a classe Aluno no hibernate.cfg.xml (que deve estar dentro do diretório WEB-INF/classes)? Assim?

&lt;mapping resource="Aluno.hbm.xml" /&gt;
pauloperes
pauloperes

Lipe, valeu por enquanto kra.

Seguinte naum entendi.

Veja, devo tenho seguintes arquivos:

Aluno.class
AlunoDAO.class
Aluno.hbm.xml

Este arquivo que você falou (hibernate.cfg.xml) eu naum tenho ele.

Eu li um artigo no GUJ para usar o hibernate, porém la a versao do hibernate é 1.xx e a q to usando é a 3.

Ja sei que tem algumas diferenças.

Tipo, vc num tem ai uma receita de bolo para usar o hibernate.

Valeu

Paulo

_fs
_fs

imagino que você esteja usando o arquivo hibernate.properties para configura-lo, certo?

Adicione um arquivo chamado hibernate.cfg.xml na pasta WEB-INF/classes, o conteudo deste arquivo é o seguinte:

<?xml version="1.0"?>
&lt;!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 2.0//EN"
	"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd"&gt;

&lt;hibernate-configuration&gt;
	&lt;session-factory&gt;
		&lt;mapping resource="meu/pacote/Aluno.hbm.xml" /&gt;
	&lt;/session-factory&gt;
&lt;/hibernate-configuration&gt;

E, a cada classe nova a ser persistida, adicione mais um elemento <mapping> neste arquivo, indicando o pacote corretamente.

Lipe,

Não tenho esta pasta, esotu no netbenas, só tenho o meu diretório com as classesm, tenho sim o hibernate.properties na própria pasta, porém na hora de rodar, da pau dizendo que naum acha o arquivo.

Vc, ja deve estar sem paciência (hehe)
Valeu
Paulo

Não estou sem paciência não :smiley:

Bem cara, não manjo de netbeans, porém, se a IDE está te atrapalhando … tire ela do caminho e crie as pastas na mão oras.
