Problemas com hibernate

Assuntos Gerais
#1

Boa noite pessoal, estou estudando sobre hibernate com annotations e me deparei com o seguinte problema:


Exception in thread "main" org.hibernate.MappingException: Unknown entity: teste.Cliente
	at org.hibernate.impl.SessionFactoryImpl.getEntityPersister(SessionFactoryImpl.java:550)
	at org.hibernate.impl.SessionImpl.getEntityPersister(SessionImpl.java:1338)
	at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:98)
	at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:187)

	at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:172)

	at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:535)
	at org.hibernate.impl.SessionImpl.save(SessionImpl.java:523)
	at org.hibernate.impl.SessionImpl.save(SessionImpl.java:519)
	at teste.HibernateDAO.salvar(HibernateDAO.java:18)
	at teste.Principal.main(Principal.java:17)

as classes que estou usando são:


package teste;
import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.Entity;



@Entity
@Table(name="CLIENTE")
public class Cliente implements Serializable{

	/**
	 * 
	 */
	private static final long serialVersionUID = 7467231787702303488L;
	
	
	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	private Long id;
	
	@Column(name="nome",nullable=false, length=60)
	private String nome;
	
	@Column(name="idade",nullable=false,length=5)
	private Long idade;

	public Cliente() {
	}

	public Long getId() {
		return id;
	}

	@SuppressWarnings("unused")
	private void setId(final Long id) {
		this.id = id;
	}

	public Long getIdade() {
		return idade;
	}

	public void setIdade(final Long idade) {
		this.idade = idade;
	}

	public String getNome() {
		return nome;
	}

	public void setNome(final String nome) {
		this.nome = nome;
	}
}
// Fim da Classe



package teste;
import org.hibernate.Session;
import org.hibernate.SessionFactory;


public class HibernateDAO {
	
	private SessionFactory factory;
	private Session session;

	public HibernateDAO() {
	}

	public void salvar(Cliente cli) {
		factory = HibernateUtil.getSessionFactory();
		session = factory.openSession();
		session.beginTransaction();
		session.save(cli);
		session.getTransaction().commit();
	}

}


package teste;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {

	private static final SessionFactory sessionFactory;
	static {
		try {
			// Create the SessionFactory from hibernate.cfg.xml
			sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
		} catch (Throwable ex) {
			// Make sure you log the exception, as it might be swallowed
			//
			//System.err.println("Initial SessionFactory creation failed. " + ex);
			System.out.println(ex.getMessage());
			throw new ExceptionInInitializerError(ex);
		}
	}

	public static SessionFactory getSessionFactory() {
		return sessionFactory;
	}

}


package teste;


public class Principal {
	
	/**
	* @param args
	*/
	public static void main(String[] args) {
	Cliente c1 = new Cliente();
	c1.setNome("Raul Seixas");
	c1.setIdade(new Long(12));
	Cliente c2 = new Cliente();
	c2.setNome("Bruce Dickinson");
	c2.setIdade(new Long(13));
	HibernateDAO hd = new HibernateDAO ();
	hd.salvar(c1);
	hd.salvar(c2);
	}

}

o hibernate.cfg.xml está da seguinte forma:


<?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>
		<!-- Database connection settings -->
		<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="connection.url">jdbc:mysql://localhost/test</property>
		<property name="connection.username">root</property>
		<property name="connection.password">root</property>
		<!-- JDBC connection pool (use the built-in) -->
		<property name="connection.pool_size">1</property>
		<!-- SQL dialect -->
		<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
		<!-- Enable Hibernate's automatic session context management -->
		<property name="current_session_context_class">thread</property>
		<!-- Disable the second-level cache -->
		<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
		<!-- Echo all executed SQL to stdout -->
		<property name="show_sql">true</property>
		
	
		<mapping class="teste.Cliente"/>
	</session-factory>
</hibernate-configuration>

se alguém puder me ajudar a resolver esse entrave…

Acredito q o problema esteja na url que vc esta passando na configuração

verifique nomes no projeto e nomes no banco.
