Estou estudando Annotations com Hibernate e me deparei com o seguinte erro:
org.hibernate.InvalidMappingException

O que é que está errado no mapeamento via annotations?

org.hibernate.util.XMLHelper$ErrorLogger error
SEVERE: Error parsing XML: XML InputStream(1) Content is not allowed in prolog.
Exception in thread "main" java.lang.ExceptionInInitializerError
        at controle.StartHibernate.&lt;clinit&gt;(StartHibernate.java:24)
        at modelo.OperacoesBanco.salvar(OperacoesBanco.java:28)
        at controle.Main.main(Main.java:20)
Caused by: org.hibernate.InvalidMappingException: Could not parse mapping document from resource

Porque isso?

Essas são minhas classes de mapeamento:

import java.io.Serializable;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
@Table(name="usuario", schema="teste")
public class Usuario implements Serializable{

    @Column(name = "nome")
    private String nome = "";


    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;    
   //meus gets e sets

}

Esse é meu banco para teste:

CREATE TABLE usuario (
  id int(11) NOT NULL auto_increment,
  nome varchar(10) default NULL,
  PRIMARY KEY  (id)
) 

CREATE TABLE dadosusuario (
  id int(11) NOT NULL auto_increment,
  dado varchar(5) default NULL,
  usuario_id int(11) NOT NULL,
  PRIMARY KEY  (id),
  FOREIGN KEY (usuario_id) REFERENCES usuario (id)
)

O que vc faz na linha 24 de StartHibernate.java?
Vc já verificou o seu arquivo hibernate.cfg.xml?

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;


public class StartHibernate {

    private static SessionFactory factory;
    private static final ThreadLocal&lt;Session&gt; tl = new ThreadLocal&lt;Session&gt;();

    static{
        try{
            factory = new AnnotationConfiguration().configure(&quot;hibernate.cfg.xml&quot;).buildSessionFactory();
        }
        catch(Throwable t){
            System.out.println(&quot;\n Erro na classe StartHibernate \n&quot;);
            throw new ExceptionInInitializerError(t);
        }
    }

    public static Session getSession(){
        Session session = (Session) tl.get();
        session = factory.openSession();
        tl.set(session);
        return session;
    }
}

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration

    &lt;mapping class="modelo.Usuario" file="" jar="" package="" resource=""/&gt;
  &lt;/session-factory&gt;
&lt;/hibernate-configuration&gt;

altere

&lt;mapping class="modelo.Usuario" file="" jar="" package="" resource=""/&gt;

para

&lt;mapping class="modelo.Usuario"/&gt;
