          PreparedStatement stmt = null;
          String sql = "SELECT l.codigo, l.nome_produto, l.composicao, DATE_FORMAT(l.data_aprovacao , '%d/%m/%Y'), co.nome as colecao, e.nome as estilista, DATE_FORMAT(l.data_inicio , '%d/%m/%Y'), DATE_FORMAT(l.data_termino , '%d/%m/%Y') from lote_producao as l INNER JOIN colecao as co INNER JOIN estilista as e ON co.codigo = l.colecao_codigo AND e.codigo = l.estilista_codigo AND l.codigo = "+codigo;
          stmt = con.prepareStatement(sql);
          ResultSet rs = stmt.executeQuery();
          JRResultSetDataSource relatResult = new JRResultSetDataSource(rs);
          JasperPrint jpPrint = JasperFillManager.fillReport("ireport/relLot.jasper", new HashMap(), relatResult);
          JasperViewer jv = new JasperViewer(jpPrint);
          jv.setVisible(true);
