Boa noite pessoal.
Preciso de ajuda com o seguinte problema.
Tenho uma pagina com um select e preciso adicionar outros campos (botões de radio, caixas de seleção, campos de texto, etc) para entrada de otros dados.
Então:
listaFabrica.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<html:html>
<body>
<head><title>Grafica Reluc - PCP - Planejamento e Controle de Producao</title></head>
<!-- Cria Lista com codigo da fabrica e o nome da fabrica-->
Fabrica:
<select name="cmbFabrica">
<c:forEach var="fabrica" items="${fabricas}">
<option value="${fabrica.cd_fabrica}"> ${fabrica.cd_fabrica} </option>
</c:forEach>
</select>
</body>
</html:html>ListaFabricaActio.java
package br.com.black.struts.action;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import br.com.black.jdbc.dao.ProducaoDAO;
import br.com.black.jdbc.modelo.Fabrica;
public class ListaFabricasAction extends Action{
@Override
public ActionForward execute(ActionMapping map, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception {
List<Fabrica> lista = new ProducaoDAO().getListaFabrica();
request.setAttribute("fabricas", lista);
// TODO Auto-generated method stub
return map.findForward("lista");
}
}struts-config.xml

</struts-config>Ok, eu tentei incluir ai nesta pagina um campo de texto simples desta forma:
Codigo:
<html:text property="fabrica.cd_fabrica"/>
<html:errors property = "cd_fabrica"/></br>
</br>Obtive este erro:
