How to attach a .pdf file to a generated Jasper report
Example: Say I have 2 jasper files, a.jasper and b.jasper. Now these 2 jasper files are exported as a pdf report
in one single pdf file. tht is Page 1 of the pdf will have a.jasper and page 2 will have b.jasper. Now this I have acheived this by using
JRExporter and passing a.jasper and b.jasper as a list. But there is
one more pdf file itself say c.pdf ( not a jasper file, as this is provided by our customer and cannot be created as a japer).
Now I want this c.pdf as the 3rd page of the exported pdf report...

This is how I did in Java. Hope this helps
ByteArrayInputStream bs = new ByteArrayInputStream(output.toByteArray()); // output refers to your Jasper report
Document document = new Document();
PdfCopy copy = new PdfCopy(document, output);
document.open();
PdfReader jasperReader; //Reader for Jasper Report
PdfReader nonJasperReader; // Reader for the Pdf to be attached (not .jasper file)
jasperReader= new PdfReader(bs);
attachmentReader = new PdfReader(params.get("att").toString());
numberOfPages = jasperReader.getNumberOfPages();
for (int page = 0; page < numberOfPages;) {
copy.addPage(copy.getImportedPage(jasperReader, ++page));
}
numberOfPages = nonJasperReader.getNumberOfPages();
for (int page = 0; page < numberOfPages;) {
copy.addPage(copy.getImportedPage(nonJasperReader, ++page));
}
copy.freeReader(jasperReader);
jasperReader.close();
document.close();
}
Thanks Thomas.
However when i see the code, i see only these lines that contribute to the output for my jasper report.
It creates a file path for the masterTemplate and then compiles it and fill and then finally export the jasperPrint object, so are you talking about the JasperPrint object ?
*****************************************************
String masterTemplate = ProductionUtils.createFilePath( config.getSystemProperty( SystemProperty.PATH_KEY ), JRXML_FILE );
jasperReport = JasperCompileManager.compileReport( masterTemplate );
jasperPrint = JasperFillManager.fillReport( jasperReport, parameters, new JREmptyDataSource() );
JasperExportManager.exportReportToPdfFile( jasperPrint, generateLocalFilePath() );
*****************************************************
I called the
JasperExportManager.exportReportToPdf(jasperPrint) - method and it returned me byteArray.</pre>
1. But what is the output in PdfCopy instance --> its an outStream? :-
PdfCopy copy = new PdfCopy(document, output); ?????????
2 . And how will i call my PdfReader for the attachmentReader as PdfReader accepts ByteArrayInputStream?
3. And after getting the 'copy', how we will pass the exportReportToFile method with a jasperPrint object?
Thanks.
