Unable to print the report using Jasper

[Shrikant Kulkarni]

Hi All,
I am using jasper reports for generating some reports. I have written one
"JasperReport.jrxml" file for report to display.
In "html.jsp" file i have written code with generates reports in html format. the code in html.jsp is as below
==================================================================

File reportFile = new File(application.getRealPath("/reports/JasperReport.jasper"));
if (!reportFile.exists())
throw new JRRuntimeException("File JasperReport.jasper not found. The report design must be compiled first.");

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

Map parameters = new HashMap();
parameters.put("ReportTitle", "Jasper Report");
JasperReportDataSource ob =new JasperReportDataSource();
//rs is Resultset of my query
ResultSet rs = ob.getResultSet();
JRResultSetDataSource jr = new JRResultSetDataSource(rs);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jr);

JRHtmlExporter exporter = new JRHtmlExporter();
session.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "../servlets/image?image=");

exporter.exportReport();

==========================================================================

When i run this application the report what i generated as just a blank even the static fields mention in .jrxml file are not displayed.

Can any one pls help me in this regard.
