Java EE (Java Enterprise Edition) General Discussion

Hi,

I am adding a jasper report to my existing web application running on top of struts 1.0.x. I managed to compile and view my report by using ireport 0.5.1. When I wrote some code to load-compile-fill-export to pdf, I encounter the following error. Can anyone help me to tell me what is going wrong?

Btw, I am using struts framework whereby the request is received and processed by the ActionForm. And from there, i pass it to a self written DAO to generate the report.

Here are the code snippet,

Inside action class
===============
public ActionForward monthlybyvenue(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {

ReportingForm rptfrm = (ReportingForm) form;
ReportDAO rptDAO = new ReportDAO();
DateUtils dutil = new DateUtils();

String searchmonthfrm = rptfrm.getSearchmonthfrm();
String searchyearfrm =rptfrm.getSearchyearfrm();

String searchmonthto = rptfrm.getSearchmonthfrm();
String searchyearto = rptfrm.getSearchyearto();

int lastDayOfMonth = dutil.getMaxDayOfMonth(Integer.parseInt(searchyearto),dutil.getIntMonth(searchmonthto));
String periodFrom = "01/" + convertMonth(String.valueOf(dutil.getIntMonth(searchmonthfrm))) + "/" + searchyearfrm;
String periodTo = lastDayOfMonth + "/" + convertMonth(String.valueOf(dutil.getIntMonth(searchmonthto))) + "/" + searchyearto;

String jasperXmlFile = request.getRealPath("/WEB-INF/classes/my/com/cni/mrbs/report/template/jrxml/monthlyRoomBookingByVenue.jrxml");
String pdfFile = request.getRealPath("/WEB-INF/classes/my/com/cni/mrbs/report/monthlyRoomBookingByVenue.pdf");

rptDAO.genPdfReport(periodFrom, periodTo, jasperXmlFile, pdfFile);

return mapping.findForward("monthlybyvenue");

}

Inside DAO class
==============
public void genPdfReport (String periodFrom, String periodTo, String designFile, String pdfFile) throws Exception{
Connection conn = null;

try {
boolean hasConnection = chkConnection();
if(!hasConnection)
conn = getConnection();
else
conn = this.globalConn;

JasperDesign jasperDesign = JRXmlLoader.load(designFile);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("date_from", Helper.str2date(periodFrom));
parameters.put("date_to", Helper.str2date(periodTo));
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);
JasperExportManager.exportReportToPdfFile(jasperPrint, pdfFile);

chkReturnConn(conn);
}catch (Exception e) {
e.printStackTrace();
throw e;

}
}


Here are the error stack,
