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 Thanks in advance..
