Conexão com o Banco usando Hibernate

Elaborei as seguintes Classes:

[code]import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {
private static final SessionFactory SessionFactory = buildSessionFactory();

private static org.hibernate.SessionFactory buildSessionFactory() {
	try {
		AnnotationConfiguration cfg = new AnnotationConfiguration();
		cfg.configure("hibernate.cfg.xml");
		return cfg.buildSessionFactory();
	} catch (Throwable e) {
		System.out
				.println("Criação inicial de objeto SessionFactory falhou. Erro: "
						+ e);
		throw new ExceptionInInitializerError(e);
	}
}
public static SessionFactory getSessionFactory(){
	return SessionFactory;
}

}[/code]

[code]import org.hibernate.Session;

public class ConectaHibernateMySQL {

public static void main(String[] args) {
	Session sessao = null;
	try {
		sessao = HibernateUtil.getSessionFactory().openSession();
		System.out.println("Conectou!");
	} finally {
		sessao.close();
	}
}

}[/code]

Com a seguinte XML:

[code]<?xml version="1.0" encoding="UTF-8"?>

org.hibernate.dialect.MySQLDialect com.mysql.jdbc.Driver jdbc:mysql://localhost/agenda root root thread

5
20
300
50
3000

true
true
true
true

	<mapping resource="com/livro/capitulo3/crudxml/Contato.hbm.xml"/>	
	<mapping class="com.livro.capitulo3.crudannotations.ContatoAnnotations"/>
[/code]

No entanto, não estou conseguindo compilar com o resultado: Conectou!

No Console o resultado é esse:

40 [main] INFO org.hibernate.cfg.annotations.Version - Hibernate Annotations 3.5.2-Final 70 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.5.2-Final 70 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found 80 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist 90 [main] INFO org.hibernate.cfg.Environment - using JDK 1.4 java.sql.Timestamp handling 342 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final 352 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: hibernate.cfg.xml 352 [main] INFO org.hibernate.cfg.Configuration - Configuration resource: hibernate.cfg.xml Criação inicial de objeto SessionFactory falhou. Erro: org.hibernate.HibernateException: hibernate.cfg.xml not found Exception in thread "main" java.lang.NullPointerException at com.livro.capitulo3.conexao.ConectaHibernateMySQL.main(ConectaHibernateMySQL.java:13)

Amigo segue a minha classe HibernateUtil:

[code]public class HibernateUtil {

public static final SessionFactory session = buildSession();

private static SessionFactory buildSession() {

try{
     Configuration cfg = new Configuration();
                   cfg.configure("hibernate.cfg.xml");

    return cfg.buildSessionFactory();

   }catch(Throwable b){

        System.out.println("Não deu \n" + b);
        throw new ExceptionInInitializerError();
   }

}

public static SessionFactory getSessionFactory(){
return session;
}[/code]

Arquivo de configuração do Hibernate

[code]<?xml version="1.0" encoding="UTF-8"?>

org.gjt.mm.mysql.Driver jdbc:mysql://localhost/banco root org.hibernate.dialect.MySQL5Dialect true true update [/code]

Classe que abre a conexão com o banco

[code]public class Teste {

/**
 * @param args
 */
@SuppressWarnings("unused")
public static void main(String[] args) {
	// TODO Auto-generated method stub
	Session sessao = HibernateUtil.getSessionFactory().openSession();
	
}

}[/code]
