+ " tbl_cliente"
);
JRResultSetDataSource jrRS = new JRResultSetDataSource(getResultSet());
InputStream caminhoRelatorio = this.getClass().getClassLoader().getResourceAsStream("C:/Projetos Java/BiaHotDog/src/relatorios");
JasperPrint jasperPrint = JasperFillManager.fillReport(caminhoRelatorio, new HashMap(), jrRS);
JasperExportManager.exportReportToPdfFile(jasperPrint, "C:/Projetos Java/BiaHotDog/rel/relatorioCliente.pdf");
File file = new File("C:/Projetos Java/BiaHotDog/rel/relatorioCliente.pdf");
