If you are using the run task you can always check the number of pages
using the rptdocument.
IReportDocument document = null;
//Open the report document
document = engine.openReportDocument("output/resample/mcb.rptdocument");
long pgcnt = document.getPageCount();

The run task creates a rptdocument that can be rendered with a render
task. It allows you to get report output meta data like table of
contents, bookmarks and number of pages. The render task can be set to
render all pages or a page at a time. This is not possible with a
runandrender task which just runs the report and renders it in one task
and does not create a rptdocument.

Are you calling the iText libraries directly? Maybe the
PdfCopyFields.addDocument will work. I have an RE API example that
combines to report outputs. I am attaching it.

Thanks a lot for the API, I've tried it and it works. For other reasons we did however choose to use an empty rpt-design instead, but I will save the API anyway 
I'm having some problem with the pageCount which in tests turned out to be not so perfect. A printout with a dynamic list that is shown on two pages still returns a pagecount of 1. Any clue why?
Here is the create-method in which I have replaced RunAndRenderTask with a RunTask and a RenderTask.
public ByteArrayOutputStream createReport(String reportDesignName, String reportDocumentName, Object reportObject, Boolean printSettingDoubleSided)
throws ReportException {
ServletContext servletContext = WebHelper.getServletContext();
ByteArrayOutputStream pdfBaos = new ByteArrayOutputStream();
IRunTask runTask = null;
IRenderTask renderTask = null;
HashMap<String, Object> appContext = new HashMap<String, Object>();
appContext.put("reportObject", reportObject);
try {
IReportEngine engine = BirtEngine.getBirtEngine();
// RUN
String designHome = servletContext.getRealPath(ReportingConstants.REPORT_DESIGN_ PATH);
log.debug("RealPath to Birt report: " + designHome);
IReportRunnable report = engine.openReportDesign(designHome + reportDesignName);
runTask = engine.createRunTask(report);
runTask.setAppContext(appContext);
String documentHome = servletContext.getRealPath(ReportingConstants.REPORT_DOCUMEN T_PATH);
runTask.run(documentHome + reportDocumentName);
// RENDER
IReportDocument reportDocument = engine.openReportDocument(documentHome + reportDocumentName);
renderTask = engine.createRenderTask(reportDocument);
renderTask.setAppContext(appContext);
HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler();
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(IRenderOption.OUTPUT_FORMAT_PDF);
options.setOutputStream(pdfBaos);
options.setImageDirectory("./images");
options.setImageHandler(imageHandler);
renderTask.setRenderOption(options);
renderTask.render();
long pageCount = reportDocument.getPageCount();
if(printSettingDoubleSided && pageCount % 2 > 0) {
//add an empty last page and concatenate into one baos
System.out.println(reportDesignName +" har udda antal sidor");
List<ByteArrayOutputStream> pdfBaosListTemporary = new ArrayList<ByteArrayOutputStream>();
pdfBaosListTemporary.add(pdfBaos);
pdfBaosListTemporary.add(createEmptyReport());
pdfBaos = concatPdfs(pdfBaosListTemporary, false);
}
reportDocument.close();
} catch(EngineException e) {
log.error(e.toString());
throw new ReportException("[createReport] Error when creating report:" + reportDesignName);
} catch(BirtException e) {
log.error(e.toString());
throw new ReportException("[createReport] Error when trying to create reportengine in creating report:"
+ reportDesignName);
} finally {
if(runTask != null) {
runTask.close();
}
if(renderTask != null) {
renderTask.close();
}
}
//return baos;
return pdfBaos;
}

Are you saying the reportDocument.getPageCount() method is only
returning 1? Can you reproduce with the sample db so I can run the
report here and have a look at it?
BTW if you are going to render to PDF you do not need to use
HTMLRenderOption. Use PDFRenderOption like:
PDFRenderOption options = new PDFRenderOption();
options.setOption(IPDFRenderOption.PDF_HYPHENATION, true);
options.setOption(IPDFRenderOption.PDF_TEXT_WRAPPING, true);
options.setOption(IPDFRenderOption.PAGE_OVERFLOW,
IPDFRenderOption.FIT_TO_PAGE_SIZE);
//options.setOption(IPDFRenderOption.DPI, 300);
options.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");
options.setOutputFileName("output/resample/file2.pdf");
options.setOutputFormat("pdf");

I need a report I can run in my debug environment to test it. That is
why I asked if you could recreate the issue with a report that uses the
classic models sample db.

You can just email it to me at jasonweathersby at windstream dot net.
The classic models db is an embedded derby database and it is included
in birt so you should not have to connect to an external db.
