public class EssaiHibernate {
 
	public Configuration config = null;
 
	public SessionFactory factory = null;
 
	public EssaiHibernate(){
 
 
		System.out.println("step 1");
		config = new Configuration();
		System.out.println("step 2");
		config.configure();
		System.out.println("step 3");
		factory = config.buildSessionFactory();
		System.out.println("step 4");
	}
	/**
