Tapestry / JasperReports App truncating RTF Output!

[Mike London]

Hello,

I have a simple Tapestry application that is (using JasperReports RTF) truncating the output of a large (~10 MB) RTF file.

Some of the RTF file is correct in Word, but after about page 1,400, I have a hundred or so blank pages (where the PDF equivalent still has correct data).

I'm using code with JasperReports like this to create the outputstream:

 

    protected byte[] exportHelper() throws JRException {
        JasperPrint print = JasperFillManager.fillReport(getCompiledReportStream(),
                getParameters(), getDataSource());
       
        JRRtfExporter exporter = new JRRtfExporter();
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
        exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);
        exporter.exportReport();
        return outputStream.toByteArray();

   

Again, the PDF version of this code works fine.

And, this code works OK for RTF if the file size is smaller.

So, I'm a bit unsure what the actual problem is.

The size of the byte array is < MAXINT so I'm OK there. I thought there might be some type of overflow issue.

I'm wondering if this could also be a word-memory issue?

Any suggestions would greatly (!!!) be appreciated.

Thanks.
