try{
String jrxmlFileName = "C:/Jasper/Dashboard2.jrxml";
JasperReport objJReport = JasperCompileManager.compileReport(jrxmlFileName);
connection = getConnection();
JasperPrint print = JasperFillManager.fillReport(objJReport, jrxmlParams, connection);
ByteArrayOutputStream outputByteArray = new ByteArrayOutputStream();
//OutputStream outputfile= new FileOutputStream(new File("c:/output/JasperReport.xls"));
JRXlsExporter exporterXLS = new JRXlsExporter();
exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, print);
exporterXLS.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "C:/Jasper/Dashboard2.xls" );
exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, outputByteArray);
exporterXLS.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
exporterXLS.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
exporterXLS.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
exporterXLS.exportReport();
//outputfile.write(outputByteArray.toByteArray());
}catch (Exception e) {
