og4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version). log4j:WARN Please initialize the log4j system properly. Exception in thread "main" org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1494) at org.hibernate.cfg.AnnotationConfiguration.doConfigure(AnnotationConfiguration.java:990) at org.hibernate.cfg.AnnotationConfiguration.doConfigure(AnnotationConfiguration.java:69) at org.hibernate.cfg.Configuration.configure(Configuration.java:1428) at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:972) at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:69) at org.hibernate.cfg.Configuration.configure(Configuration.java:1414) at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:966) at teste.TesteDeSessao.main(TesteDeSessao.java:13) Caused by: org.dom4j.DocumentException: Error on line 27 of document : The markup in the document following the root element must be well-formed.

agora segue as classes

[code]package teste;

import modelo.Produto;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.AnnotationConfiguration;

public class TesteDeSessao {

public static void main(String[] args) {
    AnnotationConfiguration configuration = new AnnotationConfiguration();
    configuration.configure();

    SessionFactory factory = configuration.buildSessionFactory();
    Session session = factory.openSession();
    
    Produto produto = new Produto();
    produto.setNome("Prateleira");
    produto.setDescricao("Uma prateleira para colocar livros");
    produto.setPreco(35.90);
    
    
    Transaction tx = session.beginTransaction();
    session.save(produto);
    tx.commit();

}

}

[/code]

[code]package modelo;

import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Entity;

@Entity
public class Produto {

@Id
@GeneratedValue
private int id;
private String nome, descricao;
private Double preco;




public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getNome() {
    return nome;
}

public void setNome(String nome) {
    this.nome = nome;
}

public String getDescricao() {
    return descricao;
}

public void setDescricao(String descricao) {
    this.descricao = descricao;
}

public Double getPreco() {
    return preco;
}


public void setPreco(Double preco) {
    this.preco = preco;
}

}
[/code]

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

root jdbc:mysql://localhost/fj28 com.mysql.jdbc.Driver org.hibernate.dialect.MySQL5InnoDBDialect update true 
    <mapping class="modelo.Produto" />
</session-factory>
[/code]

O problema está no seu hibernate.cfg
tenta colocar esse daqui, mudando as propriedades da sua aplicacao:

<?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>
	
		<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="hibernate.connection.url">jdbc:mysql://localhost/fj28</property>
		<property name="hibernate.connection.username">root</property>
		<property name="hibernate.connection.password"></property>
		<property name="hibernate.hbm2ddl.auto">update</property>
		<property name="hibernate.show_sql">true</property>
		<property name="hibernate.format_sql">true</property>
		<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

		
 		<mapping class="modelo.Produto" />
	</session-factory>

</hibernate-configuration>
