            int cod = Integer.parseInt(scod);
               try{
         Metodos.conexaobd conexao = new Metodos.conexaobd();
            
            Connection con = null;
            
           
            
            HashMap param = new HashMap();
            
            param.put("cod_cliente",cod);
            
            JasperPrint rel = null;
            
            rel = JasperFillManager.fillReport("C:\\Users\\Maquina001\\Documents\\NetBeansProjects\\Caixas\\src\\Relatórios\\Rel_porselecao.jasper", param, conexao.conectar());
            
            JasperViewer.viewReport(rel, false);
            
            
        }catch(Exception e )
        {
            JOptionPane.showMessageDialog(null,e.getMessage(),"SOFTWELL",JOptionPane.ERROR_MESSAGE);
