Olá pessoal,essa é a minha primeira vez aqui…
bom,o meu problema é o seguinte:
estou criando um projeto web no Netbeans p/ faculdade que usa o padrão MVC,tô me guiando pela apostila da caelum só que não tá adicionando no banco,já olhei várias vezes e não tô enxergando o erro
segue o código p/ vcs analizarem:
lógica
package br.com.marcos.mvc.logica;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

* @author marcos
*/
public interface Logica {
void executa (HttpServletRequest req, HttpServletResponse res)throws Exception;
}cadastro de propriedade:
package br.com.marcos.mvc.logica;
import br.com.marcos.mvc.bean.PropriedadeBean;
import br.com.marcos.mvc.dao.PropriedadeDao;
import javax.servlet.RequestDispatcher;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

*/
public class CadastraPropriedade implements Logica {
public void executa(HttpServletRequest req, HttpServletResponse res) throws Exception {
PropriedadeBean pr = new PropriedadeBean();
pr.setNome(req.getParameter("nomepropriedade"));
pr.setEndereco(req.getParameter("endereco"));
pr.setBairro(req.getParameter("bairro"));
pr.setCidade(req.getParameter("cidade"));
pr.setUf(req.getParameter("uf"));
pr.setCep(Long.parseLong(req.getParameter("cep")));
pr.setCnpj(Long.parseLong(req.getParameter("cnpj")));
pr.setTelefone(Long.parseLong(req.getParameter("telefone")));
PropriedadeDao prc = PropriedadeDao.getInstancePropC();
prc.cadastrarPropriedade(pr);
RequestDispatcher rd = req.getRequestDispatcher("/propriedade-adicionada.jsp");
rd.forward(req, res);
System.out.println("Cadastro " +pr.getNome()+"sendo adicionado,por favor verifique o banco");
}
}
