Jasper report exports empty data in PDF format when there is more data

Question

I have a report to be exported in excel, pdf and word using jasper reports. I use xml file as the DataSource for the report, but when the data increases jasper report exports empty file in only for PDF format, when i reduce the data content it export the data available correctly. is there any limitation to pdf size? , how can we manage the size in jasper reports from java?

My jrxml is really big, so i cannot add it here, i have added my java code which i use to export the content:-

JRAbstractExporter exporter = null; if (format.equals("pdf")) { exporter = new JRPdfExporter(); jasperPrint.setPageWidth(Integer.parseInt( pWidth )); } else if (format.equals("xls")) { exporter = new JRXlsExporter();

  } else if (format.equals("doc")) {    jasperPrint.setPageWidth(Integer.parseInt( pWidth ));
  }

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream_); exporter.exportReport(); contents = outputStream_.toByteArray(); response.setContentType("application/"+format); response.addHeader("Content-disposition", "attachment;filename=" + name.toString() + "."+format);

Answer 1

Try setting the content length:

response.setContentLength(outputStream_.toByteArray().length)

See if this resolves your problem.

Answer 2

maybe you don´t have data defined in report.

try this code when generating report to avoid hiding sections when no data:

JasperReport jasperReport = (JasperReport)JRLoader.loadObject ("report1.jasper"); jasperReport.setWhenNoDataType(WhenNoDataTypeEnum.ALL_SECTIONS_NO_DETAIL);

cheers!.
