Hi, (sorry for my English, it's terrible)
If you try do this, maybe solve you problem:
JasperPrint jPrint =
JasperFillManager.fillReport(reportFile.getPath(),parameters,con);
if(jPrint.getPages().size() > 0)
{
//JasperExportManager.exportReportToPdf(jPrint);
//or
JRPdfExporter exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT jPrint);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, baos);
exporter.exportReport();
byte[] bytes = baos.toByteArray();
.....
}

{
//empty report handler
}

Anybody.......PLEASE HELP me solve this problem.

Hi all,
I am using JasperPrint.getPages().size() to determine if the report has
data in it or not.
Depending on the result I m forwarding it to an error page if it doesn't
have data.
It works fine with html and excel format. However, if I am unable to use it
in my pdf report as in my pdf report it doesn't return a jasper print object
, it returns bytes.
Below is the code for my pdf servlet.
Would anybody please help me as to how can I determine if teh report has any
data or not in my pdf format.
Thanks & Regards,
Meenakshi.
bytes =
JasperRunManager.runReportToPdf(
reportFile.getPath(),
parameters,
con);
response.setContentType("application/pdf");
response.setContentLength(bytes.length);
ServletOutputStream ouputStream =
response.getOutputStream();
ouputStream.write(bytes, 0, bytes.length);
ouputStream.flush();
ouputStream.close();
}
