PDF issues

[mp_we]

Hello,

 

I have a servlet that does the following

Code:

JasperReport jsr = (JasperReport)JRLoader.loadObject("mainReport.jasper"«»);
JasperReport subReports = (JasperReport)JRLoader.loadObject("subReport.jasper"«»);
...................adding other subreports
File xmlMainReportSource = new File("MainReportSource.xml"«»);
JRDataSource subReportDataSource = new JRXmlDataSource(new File(SubReportSource.xml)"«»));
...................adding other subreport sources

//Preparing parameters
Map parameters = new HashMap();
parameters.put("DataSubreport", subReports);
parameters.put("DataSubreportSource",subReportDataSource);
..................adding all subreports and subreport sources

Document document = JRXmlUtils.parse(xmlMainReportSource);
parameters.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, document);

JasperPrint jprint = JasperFillManager.fillReport(jsr, parameters);
JasperExportManager.exportReportToPdfFile(jprint, "demo.pdf"«»);

 

If the source XMLs are small in size, the PDF (approx 20 K) gets created and displays content. If any of the source XMLs are large in size, the PDF gets created but displays blank.

 

If anyone has any ideas on what I could try to correct this, please let me know.

Thanks.
