Jasper report - Change Page Orientation

[az ziz]

dear all,

I am exporting a jasper report to a pdf. A single pdf ma be generated by more than one jasper file. so i am exporting the all the jaspers to a byte stream and join all the stream to form a single pdf file.
the problem is any of the jaspers may have a different orientation, say landscape, so when i generate a pdf the pdf has only the portrait for landscape pages too. so many of the data are out of the page. what may be the problem? i tried to change the orientation but nothing reflects in output.

 

while(something)

jasperReport = (JasperReport) JRLoader.loadObject("path/a.jasper");
JasperFillManager.fillReport(jasperReport, new HashMap(), new JRBeanCollectionDataSource(data));
if(jasperbean.getPageWidth()>0) //this is for my check
       jasperPrint.setPageWidth(jasperInfo.getPageWidth());
if(jasperbean.getPageHeight()>0)  //this is for my check
       jasperPrint.setPageHeight(jasperInfo.getPageHeight());
byte[] pdfBytes = JasperExportManager
						.exportReportToPdf(jasperPrint);
				pdfData.add(new ByteArrayInputStream(pdfBytes));
pdfData.add(new ByteArrayInputStream(pdfBytes)); //add to arrarylist
}

joinPDFs(pdfData, fileName, true); //combine and save as pdf

what to do?

thanks for your replies

You'll need to change the orientation as needed before you export.

  jasperPrint.setOrientation(OrientationEnum.LANDSCAPE);
