export to pdf creates balnk page

Go to solution Solved by lucianc,

I've try to create pdf from jrxml inside StringBuffer. I do it by converting Stringbuffer -> String -> bytes[] -> ByteArrayInputStream -> JasperCompileManager.compileReport( stream )


It creates balnk file.

However, if I write stream to the file and try to convert file to pdf, it works fine.


Is anybody can tell me what the reason of this.

        byte[] bytes = buf.toString().getBytes();
InputStream stream = new ByteArrayInputStream( bytes );

//Convert stream to Jasper Report and JasperReport to PDF
JasperReport jasperReport;
JasperPrint jasperPrint;
StringBuffer result;
try {
jasperReport = JasperCompileManager.compileReport( stream );
jasperPrint =
jasperReport, new HashMap(), new JREmptyDataSource() );
bytes = JasperExportManager.exportReportToPdf( jasperPrint );
result = new StringBuffer( new String( bytes) );
LOG.info( "Summary file created rn" );
} catch (JRException e) {
result = new StringBuffer();
LOG.info( "Summary creation failed rn" + e );
buf = new StringBuffer();
return result;
