Olá a todos,
quando tento usar o comando:
emf = Persistence . createEntityManagerFactory ( "AprendendoHibernatePU" );
é gerado um exception na minha aplicação.
Meu código está assim:
package teste.dao ;
import javax.persistence.EntityManager ;
import javax.persistence.EntityManagerFactory ;
import javax.persistence.Query ;
import javax.persistence.Persistence ;
import bean.Categoria ;
import java.util.List ;
public class CategoriaDAO {
private EntityManagerFactory emf ;
private EntityManager em ;
public CategoriaDAO () {
emf = Persistence . createEntityManagerFactory ( "AprendendoHibernatePU" );
em = emf . createEntityManager ();
}
public void gravar ( Categoria cat ) {
em . persist ( cat );
}
...
Eu chamo ele assim:
CategoriaDAO cadastro = new CategoriaDAO ();
neste momento acontece o exception

Estou usando Hibernate 3.2, Hibernate-entitymanager-3.3.1.GA e MySQL com as jar adicionado na biblioteca do netbeans. O persistence.xml estou gerando automaticamente pelo netbeans (New -> Entity Classes form Database…) e já conferi o unit no xml e está ok:
< persistence - unit name = "AprendendoHibernatePU" transaction - type = "RESOURCE_LOCAL" >
alguma sugestão?
obrigado
