Pdf Render Problem

[mehrab]

Hi all
I update my application from BIRT 2.1 to BIRT 2.3 and find a porblem when render a report in pdf. Previously it was working properly. My code and error is as follows. please anybody help me.

CODE:

public ByteArrayOutputStream getReport(File rptDocFile,
HttpServletRequest request) throws ViewerServletException {


IReportEngine engine = null;
IReportDocument iReportDocument = null;
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

try {
engine = BirtEngine.getBirtEngine();
iReportDocument = engine.openReportDocument(rptDocFile.getAbsolutePath());
IRenderTask renderTask = engine.createRenderTask(iReportDocument);
PDFRenderContext renderContext = new PDFRenderContext( );
HashMap contextMap = new HashMap();
contextMap.put(EngineConstants.APPCONTEXT_PDF_RENDER_CONTEXT,renderContext);
renderTask.setAppContext(contextMap);
// Set Render Options

HTMLRenderOption renderOption = new HTMLRenderOption();
renderOption.setOutputStream(byteArrayOutputStream);
renderOption.setOutputFormat("pdf");
renderOption.setEmbeddable(true);
renderTask.setRenderOption(renderOption);

renderTask.render();
renderTask.close();
//closing the document file after finish the work
iReportDocument.close();

} catch (BirtException e) {
log.debug("PdfReportView:"+e);
throw new ViewerServletException(e.getMessage(),e);
}
return byteArrayOutputStream;
}

Hi mehrab,

Is that the entire error stack?

Hi Michael

thanks for reply. yes that is the entire error stack. I am using BIRT with Spring Framework. So I add all BIRT plugins and libraries in following locations of my application. WEB-INF>platform>plugins, WEB-INF>platform>configuration and WEB-INF> lib.
