Good afternoon,
I have posted this same problem on the JasperForge forums, located at:
http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=93205
The error is only occurring when I turn on the PDF 508 tags, and I thought that
perhaps some additional info may be found here. Below is a description of the
problem I'm encountering and the stacktrace.
--------------------
Hello,
I have been tasked with producing a Proof of Concept surrounding the ability to
produce extremely large reports. We have been using the Jasper engine within
an in-house reporting system coupled with iReports, since version .0.6.4. We
have recently been asked by our clients to enhance the reporting engine to run
reports that would easily exceed 1GB in size in PDF format.
I'm currently using version 3.7.0 of the Jasper engine and has the following
code snippets generating the report.
I'm able to generate a report in PDF I have the compression tag set within the
exportReportToPdfFile, and use the virtualizer. However, when I add the
following tags to turn on the 508 PDF tags, the swap file finishes
successfully, but at 75-90 MB during the PDF generation I take an OutOfMemory
exception.
I have exhausted nearly every alternative I can think of, but know that the
problem is somehow tied to the actual PDF generation piece, the fillReport is
completing and greating a 3.7GB swap file. The largest report I was able to
run, without tags turned on was 1.15GB, took 9 hrs to run, with a total of
623,057 pages, but when I turned the tags on it didn't complete.
Is it trying to create the PDF file in memory only? I have tried dropping
Jasperreports' 4.1.2 iText library into the 3.7.0 Jasper engine, version 2.1.7,
but the same error occurs. This doesn't appear to be an issue related to the
virtualizer, however, do the above parameters for the swapFile and invoking the
virtualizer look practical? Any assistance would greatly appreciated.
----------------------------JRSwapFile swapFile = new JRSwapFile(tempdir, 4096
, 4096); System.out.println("Initializing report virtualizer"); virtualizer =
new JRSwapFileVirtualizer(300, swapFile, true);
parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer);
System.out.println("parameters: " + parameters);
System.out.println("virtualizer parameter set - starting pdf creation"); long
start = System.currentTimeMillis(); System.out.println("fillreport file name: "
+ qc.getAppProperty("ReportDir") + "/" + rpt); JasperPrint jasperPrint =
JasperFillManager.fillReport(qc.getAppProperty("ReportDir") + "/" + rpt,
parameters, conn); System.out.println("fillreport time : " +
(System.currentTimeMillis() - start)); start = System.currentTimeMillis();
System.out.println("beginning PDF export");
JasperExportManager.exportReportToPdfFile(jasperPrint, tempdir + "/" + qr.queID
+ "." + ext); System.out.println("PDF creation time : " +
(System.currentTimeMillis() - start)); /////////////////////////////
