[RESOLVIDO]MappingException: invalid configuration

Pessoal, estou tentando trabalhar com hibernate aqui, criei o schema do banco no mysql, e marquei nas configurações, pro hibernate criar as tabelas só que venho enfrentando esse probleminha acima.. criei uma classe pra mapear, apenas pra fazer alguns testes da seguinte forma:

CategoriaModel.java

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
@Table(name=&quot;CategoriaModel&quot;)
public class CategoriaModel {
    
    @Id
    private int codigo;
    private int tipo;
    private int quantidadeMaxima;
    private Double valorHora;
    private Double valorDiaria;
    private Double valorMensalidade;
//...continua

e o meu arquivo de configuração da seguinte forma: hibernateconfig.xml

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"&gt;
&lt;hibernate-configuration&gt;
 &lt;session-factory name=""&gt;
  &lt;property name="hibernate.connection.driver_class"&gt;org.gjt.mm.mysql.Driver
&lt;/property&gt;
  &lt;property name="hibernate.connection.url"&gt;jdbc:mysql://localhost:3306/db
&lt;/property&gt;
  &lt;property name="hibernate.connection.username"&gt;root&lt;/property&gt;
  &lt;property name="hibernate.connection.password"&gt;nxsinter&lt;/property&gt;
  &lt;property name="hibernate.hbm2ddl.auto"&gt;create&lt;/property&gt;
  &lt;mapping class="br.com.estacdione.CategoriaModel"/&gt;
  
 &lt;/session-factory&gt;
&lt;/hibernate-configuration&gt;

No entanto, tenho as seguintes msg de erro:

Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: org.hibernate.MappingException: invalid configuration
Caused by: org.xml.sax.SAXParseException: Document is invalid: no grammar found.

Alterei o xml pra esse abaixo:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"&gt;
  
&lt;hibernate-configuration&gt;  
    &lt;session-factory&gt;  
     &lt;property name="hibernate.dialect"&gt;org.hibernate.dialect.MySQLDialect&lt;/property&gt;  
     &lt;property name="hibernate.connection.driver_class"&gt;com.mysql.jdbc.Driver&lt;/property&gt;  
        &lt;property name="hibernate.connection.url"&gt;jdbc:mysql://localhost:3306/db&lt;/property&gt;  
        
        &lt;property name="hibernate.connection.username"&gt;root&lt;/property&gt;  
        &lt;property name="hibernate.connection.password"&gt;nxsinter&lt;/property&gt;  
        &lt;!-- JDBC connection pool (use the built-in) --&gt;  
        &lt;property name="connection.pool_size"&gt;1&lt;/property&gt;  
        &lt;!-- SQL dialect   
        &lt;property name="dialect"&gt;org.hibernate.dialect.PostgreSQLDialect&lt;/property&gt;--&gt;  
        &lt;!-- Enable Hibernate's automatic session context management --&gt;  
        &lt;property name="current_session_context_class"&gt;thread&lt;/property&gt;  
        &lt;!-- Disable the second-level cache --&gt;  
        &lt;property name="cache.provider_class"&gt;org.hibernate.cache.NoCacheProvider&lt;/property&gt;  
        &lt;!-- Echo all executed SQL to stdout --&gt;  
        &lt;property name="show_sql"&gt;true&lt;/property&gt;  
        &lt;!-- Drop and re-create the database schema on startup  
        tem que deixar essa propriedade ativa apos alguma modificação nas  
        tabelas ou no mapeamento, e depois comentar novamente, pois ela apaga  
        o que tem na tabela --&gt;  
        &lt;property name="hbm2ddl.auto"&gt;create&lt;/property&gt;  
        &lt;mapping class="br.com.estacione.model.CategoriaModel"/&gt;                  
    &lt;/session-factory&gt;  
&lt;/hibernate-configuration&gt;
