[jasperreports-questions] Error MEssage printing using JasperPrint Object

2006-01-11 Thread Meenakshi Singh 
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();


}

Hi,

Do not generate PDF content directly.
First call the fillReport method and produce the JasperPrint object.
Then, depending on the number of pages, you export to PDF or not.
If you say it works with HTML and XLS, then you should do exactly the 
same thing with PDF.


I hope this helps.

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();

.

 }
else
{
   //empty report handler
}
