Pessoal estou com um problema… comecei a mexer com hibernate. .dai fiz o seguinte exemplo
Artigos.java
package cadastro;
public class Artigos {
private int codigo;
private String assunto;
private String conteudo;
private int prioridade;
public String getAssunto() {
return assunto;
}
public int getCodigo() {
return codigo;
}
public String getConteudo() {
return conteudo;
}
public int getPrioridade() {
return prioridade;
}
public void setAssunto(String assunto) {
this.assunto = assunto;
}
public void setCodigo(int codigo) {
this.codigo = codigo;
}
public void setConteudo(String conteudo) {
this.conteudo = conteudo;
}
public void setPrioridade(int prioridade) {
this.prioridade = prioridade;
}
Artigos.hbm.XML
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

ArtigosDAO.JAVA
package cadastro;
import org.hibernate.Session;
public class ArtigosDAO {
public void insert(Artigos artigo) throws Exception{

session.beginTransaction();
session.save(artigo);
session.getTransaction().commit();
}
}
HibernateUtil.java
package cadastro;

throw new ExceptionInInitializerError(ex);
}
}

}
}

}
}
utilizo netbeans e a estrutura de diretorio esta assim
dentro do pacote CADASTRO estao todas as classes menos o hibernate.cfg.xml q nao esta em nenhum pacote( esta um diretorio antes )
e recebo o seguinte erro:
<blockquote>log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
