Org.hibernate.MappingException: Unknown entity: vo.Empresa

jloMatheus · Setembro 28, 2010, 11:38pm

Fala galera…
to tendo esse problema e to fuçando pra ver se encontro alguma solução…aparentemente ao meu ver está tudo correto…
to seguindo um tutorial sobre Hibernate e implementando com alguns codigos.
me deparei com esse problema de mapping do Hibernate

tenho essa classe main

import org.hibernate.Session;
import vo.Empresa;

 public class main {
     public static void main(String[] args) {
         HibernateUtil util = new HibernateUtil();
         Session session = util.getSession();
         Empresa a = new Empresa();
         a.setNmFantasia("jose");
         session.beginTransaction();
         session.save(a); 
         session.getTransaction().commit(); 
         System.out.println(a.getIdEmpresa());

         
     }
 }

o stack trace e as info do hibernate que a classe gera…

vou postar aqui o hibernate.cfg.xml,o HibernateUtil e o bean Empresa do meu projeto tambem…

hibernate.cfg.xml

HibernateUtil


public class HibernateUtil {

     private final SessionFactory sessionFactory;

     public HibernateUtil () {
         try {
             this.sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
         } catch (Throwable ex) {
             throw new ExceptionInInitializerError(ex);
         }
     }

     public Session getSession() throws HibernateException {
         return this.sessionFactory.openSession();
     }

}

Empresa.java

    }

}

o engracado é… esse meu projeto funciona em um netbeans instalado no computador de um colega meu… porem comigo nao rola…

Olá!
Tente com esta configuração no seu HibernateUtil:

public class HibernateUtil {

	private static SessionFactory factory;

	static {
		AnnotationConfiguration cfg = new AnnotationConfiguration();
		cfg.addAnnotatedClass(Empresa.class);
		factory = cfg.buildSessionFactory();
	}

	public Session getSession() {
		return factory.openSession();
	}
}

opa… então Guevara

se eu colocar o HibernateUtil do jeito que você disse ele me apresenta o seguinte stack trace:

Exception in thread "main" java.lang.ExceptionInInitializerError
        at main.main(main.java:15)
Caused by: org.hibernate.HibernateException: Hibernate Dialect must be explicitly set

        at HibernateUtil.<clinit>(HibernateUtil.java:24)
        ... 1 more

a impressão que eu tenho é que ele não ta lendo o hibernate.cfg.xml corretamente.

Guevara · Setembro 29, 2010, 12:31am

Sem problemas, use este xml:

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>
		<property name="connection.url">jdbc:postgresql://localhost/meuprojeto</property>
		<property name="connection.driver_class">org.postgresql.Driver</property>
		<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>	
		<property name="connection.username">postgres</property>
		<property name="connection.password">123456</property>				
		<property name="connection.pool_size">1</property>
		<property name="current_session_context_class">thread</property>
		<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
		<property name="hibernate.show_sql">true</property>
		<property name="hibernate.format_sql">true</property>
		<property name="hibernate.hbm2ddl.auto">update</property>
		<mapping class="br.com.meuprojeto.bean.MinhaClasse"/>		
		<mapping class="br.com.meuprojeto.bean.MinhaOutraClasse"/>					
	</session-factory>
</hibernate-configuration>

Substitua o que precisar, o banco, as classes, a senha e usuario.

jloMatheus · Setembro 29, 2010, 12:59am

não deu certo…

coloquei esse xml e alterei meu banco…ele continuou com o mesmo erro…

Guevara · Setembro 29, 2010, 1:06am

Se o erro é com o dialeto, então faltou vc alterar aquela linha lá:

hibernate.dialect org.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class com.mysql.jdbc.Driver
hibernate.connection.url jdbc:mysql://localhost/meuprojeto

Se for MySQL é isso ai. Colocou o jar do mysql dentro da sua /lib ?

jloMatheus · Setembro 29, 2010, 1:17am

Eu uso o Oracle 10g XE

ficou assim olha:


         <property name="connection.url">jdbc:oracle:thin:@localhost:1521/XE</property>
         <property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
         <property name="dialect">org.hibernate.dialect.OracleDialect</property>

Guevara · Setembro 29, 2010, 1:25am

Putz, foi mal, confundi com o outro tópico que está abaixo do seu q é MySQL.
Deixa assim então:

hibernate.dialect org.hibernate.dialect.Oracle10gDialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.url jdbc:oracle:thin:@localhost:1522:XE

Se for versão 10g é isso ai, se for 8 ou 9, é assim:

hibernate.dialect org.hibernate.dialect.Oracle8iDialect
hibernate.dialect org.hibernate.dialect.Oracle9iDialect

jloMatheus · Setembro 29, 2010, 2:10pm

é a 10g… eu só me pergunto porque em um netbeans ele funciona corretamente e no outro não…

alguma configuração errada?
permissão de usuario? lembrando que funciona no 32 bits e no 64 nao…

usei o hibernate tools nesse netbeans de 64 bits e tambem não funcionou…
