O que pode ser?

#2

Como é que vc está criando o seu Session? Como está o seu hibernate.cfg.xml ?

#3

Quando chamo o método em negrito
public List consultarTabela(String tabela)
{
session = ConnectDB.getInstance();
List lista = session.createQuery("from " + tabela ).list();
return lista;
}

classe que faz a conexão

package utils;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
//responsável por acessar os metadas acessados por anotações
import org.hibernate.cfg.AnnotationConfiguration;
//responsável por identificar qual a abordagem para o mapeamento das classes
import org.hibernate.cfg.Configuration;

/**
*

  • @author tom
    */
    public class ConnectDB
    {

private static final SessionFactory sessionFactory;
private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();

static {
try {
Configuration configuration = new AnnotationConfiguration();
configuration.configure(“hibernate.cfg.xml”);
//
sessionFactory = configuration.buildSessionFactory();
} catch (Throwable t) {
throw new ExceptionInInitializerError(t);
}

}

public static Session getInstance()
{
Session session = (Session) threadLocal.get();
session = sessionFactory.openSession();
threadLocal.set(session);
return session;
}

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

hibernate.cfg.xml

<?xml version=“1.0” encoding=“UTF-8”?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd”>
<hibernate-configuration>
<session-factory name=“exemplo_hibernate”>
<property name=“hibernate.connection.driver_class”>com.mysql.jdbc.Driver</property>
<property name=“hibernate.connection.password”>usuario</property>
<property name=“hibernate.connection.url”>jdbc:mysql://localhost/hibernate</property>
