[haideralikhan]

the single report is working fine, but not subreport 

 

Is there any "privilege" or accessing  issue ?

Code:

 



    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,

                                 HttpServletResponse response)

            throws Exception {

        try {

            Map parameters = request.getParameterMap();



            boolean recordPageDisplayFlag = false;

            String[] reportType = (String[]) parameters.get("reportType");



            //Some time we need report format (without data)

            String[] noRecordPageDisplayFlag = (String[]) parameters.get("noRecordPageDisplayFlag");



            JasperPrint jasperPrint = generateReportMgr.getReport(Integer.parseInt(reportType[0]), parameters);



            response.setContentType("application/pdf");

            ServletOutputStream outStream = response.getOutputStream();



            JRPdfExporter exporter = new JRPdfExporter();

            exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT, jasperPrint);

            exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, outStream);

            exporter.exportReport();



            outStream.flush();

            outStream.close();



            return null;

        }

        catch (Exception e) {

            e.printStackTrace();

            logger.error(e.getMessage());

            return mapping.findForward("errorPage");

        }

    }

Do you have a full exception stacktrace (including Caused by..)?
