org.hibernate.MappingNotFoundException

[Fabio Araujo]

I'm learning Hibernate and can't go through this error

Exception in thread "main" org.hibernate.MappingNotFoundException: resource: entidades.Aluno not found

hibernate.cfg.xml

As I read, if I use annotations I wouldn't use xml files to map my class...
Then my class looks like that.

package entidades;

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

@Entity
public class Aluno {
	@Id
	@GeneratedValue
	private int id;
	private String nome;
	private int idade;
	
	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 int getIdade() {
		return idade;
	}
	public void setIdade(int idade) {
		this.idade = idade;
	}
}

Where the error shows up.

package exec;

import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class CreateDB {
	
	public static void main(String[] args){
		AnnotationConfiguration configuration = new AnnotationConfiguration();
		configuration.configure();
		SchemaExport se = new SchemaExport(configuration);
		se.create(true, true);
		System.out.println("Finished!");
	}
}

Below my archives in eclipse.

Wouldn't

<mapping resource="entidades.Aluno"/>

be

<mapping class="entidades.Aluno"/>

?
