o codigo do geral-dao eh:

package dao;

import java.util.Collection;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.Transaction;
import database.Database;
import java.util.Collection;

public class GeralDAO {
//Operacoes generalizadas
protected static final int INSERIR = 1;
protected static final int ATUALIZAR = 2;
protected static final int REMOVER = 3;
//Sessao com o hibernate
private Session session;
public GeralDAO(){
session = Database.getInstance().getSession();
}
public GeralDAO(Session sessao){
session = sessao;
}

//Retorna sessao
protected Session getSession() {
if (session == null) {
session = Database.getInstance().getSession();
}
return session;
}
//Fecha sessao
protected void closeSession(){
if (session != null)
session.close();
}

public void change(Object obj, int operacao){
switch (operacao) {
case INSERIR:
case ATUALIZAR:
session.saveOrUpdate(obj);
break;
case REMOVER:
session.delete(obj);
break;
}
}

//Persiste objeto
public void create(Object obj){
change(obj, INSERIR);
}
//Atualiza objeto
public void update(Object obj){
change(obj, ATUALIZAR);
}
//Remove objeto
public void delete(Object obj){
change(obj, REMOVER);
}
//Busca pela chave primária
public Object findByPrimaryKey(Class classe, int id){
return session.get(classe, id);
}

public Collection findAll(Class classe){
try{
Criteria criteria = getSession().createCriteria(classe);
return criteria.list();
}finally{
getSession().close();
}
}

}
