Olá,

estou com um projeto web usando JNDI para acesso do abnco faz me parece que não está se conectando ao banco
e fiz um main para ver se está se conectando mais sai por erro …



package util;

import org.hibernate.Session;

public class ConectaHibernateMysql {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Session sessao=null;
		try {
			 sessao=HibernateUtil.getSessionfactory().openSession();
			 System.out.println("Conectou....ok");
		} catch (Throwable e) {
			 System.out.println("Erro ao conectar ao banco de dados..."+e.getMessage());
			 System.out.println("Erro ao conectar ao banco de dados..."+e);
		}finally{
			sessao.close();
		}

	}

}
---------------------
package util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

	private static final SessionFactory sessionFactory = buildSessionFactory();
	private static SessionFactory buildSessionFactory(){
		try {
			
			Configuration cfg = new Configuration();
			//AnnotationConfiguration cfg = new AnnotationConfiguration();
			
			cfg.configure("hibernate.cfg.xml");
			return cfg.buildSessionFactory();
		} catch (Exception e) {
			System.out.println("Criação Inicial do objeto SessionFactory falhou .Erro :"+e);
		}
		return getSessionfactory();
	}
	
	public static SessionFactory getSessionfactory(){
		return sessionFactory;
	}
}
