[Resolvido] jsf + hibernate

Front-end
#1

opa galera seguinte… to com um problema aki… to fazendo uma consulta com intervalo de datas o hibernate consegue fazer a consulta e retornar a lista com os dados mas na hora que eu percorro a lista jogando em um outro objeto ele da erro

meu bean

[code]public List verRelatorio() {

String data1 ;  
String data2 ;
		     
 DateFormat dtOutput = new SimpleDateFormat("yyyy-MM-dd");  
 data1 = dtOutput.format(caixa.getDataInicial());
 data2 = dtOutput.format(caixa.getDataFinal());
 
	HibernateDao<OrdemDeServico> hibernateDao = new HibernateDao<OrdemDeServico>(OrdemDeServico.class);
	
	ordensDeServico = hibernateDao.getListData(data1, data2);		
	
	for (int i = 0; i < ordensDeServico.size(); ++i) {
		ordemDeServico = ordensDeServico.get(i);
		valor = caixa.getValorDiario()	+ ordemDeServico.getValorTotal();
	}
	
	System.out.println("AKIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIii        "+caixa.getValorDiario());
	
	System.out.println("AKIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIii        "+valor);
	
	return null;
}[/code]

meu dao do hibernate

public List<T> getListData(String data3, String data4){ Session session = HibernateUtil.getSf().getCurrentSession(); session.beginTransaction(); List<T> beans = (List<T>) session.createSQLQuery("SELECT * FROM OrdemDeServico WHERE dataFechamento BETWEEN '"+data3+"' AND '"+data4+"'").list(); session.getTransaction().commit(); return beans; }

o erro desgraçado

#2

Como que você está percorrendo a lista?

#3

assim

for (int i = 0; i < ordensDeServico.size(); ++i) {
ordemDeServico = ordensDeServico.get(i);
valor = caixa.getValorDiario() + ordemDeServico.getValorTotal();
}

#4

é nessa hora que da o erro eu fiz um debub e o erro da quando faço isso ordemDeServico = ordensDeServico.get(i);

#5

Onde vc declarou ordemDeServico?

#6

o problema está sendo no cast que você está tentando dar de object para OrdemDeServico

Tente fazer assim

        }

#10

Como o fabiozanardi já falou, o problema está no cast.

Verifique se sua lista está retornando mesmo a classe ordemdeservico em vez de um object.

#11

sim ja verifiquei ele retorna os dados certos em forma de lista… o problema ocore quando eu faço isso
ordemDeServico = ordensDeServico.get(i);

ele gerra a exception

#12

o problema é o Cast de Object para Ordem de serviço

verifique se o retorno do método ordensDeServico.get(…) é do mesmo tipo do seu objeto ordemDeServico

#13

resolvi galera vlw pela ajuda problema era no DAO

	List<T> beans = (List<T>) session.createQuery("FROM OrdemDeServico WHERE dataFechamento BETWEEN '"+data3+"' AND '"+data4+"'").list();
#14

Tente trocar

List<T> beans = (List<T>) session.createSQLQuery("SELECT * FROM OrdemDeServico WHERE dataFechamento BETWEEN '"+data3+"' AND '"+data4+"'").list();

por

List<T> beans = (List<T>) session.createQuery("FROM OrdemDeServico WHERE dataFechamento BETWEEN '"+data3+"' AND '"+data4+"'").list();
#15

Boa!!

#16

era isso mesmo TCHACO antes de vc responder fiz isso e deu certo obrigado

#17

era isso mesmo tchaco vlww
