Jasper report export to xls is blank always even for simple report

Question

I'm unable to export my jasper report in Excel format but the same works fine for pdf. Below is my code snippet.. Kindly let me know where I'm going wrong

out = response.getOutputStream();

jasperReport = JasperCompileManager.compileReport(filePath + fileName);

jasperPrint = JasperFillManager.fillReport(jasperReport, jasperParam, connection);

JRXlsExporter exporterXLS = new JRXlsExporter();

exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint);

exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, out);

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();

I'm using the below jars,

jasperreports-6.1.0.jar poi-3.9-20121203.jar

commons-digester-1.7.jar jfreechart-1.0.14.jar joda-time-2.4.jar
