Displaying empty pdf with jasper reports using spring framework

Hi,

I am working with spring jasper integration to generate the jasper reports. Spring 3.0.5RELEASE,ireport 4.5.0

I generated a report template using the ireport.My spring controller class is returning the view and i am using the view resolver in the dispatcher-servlet.xml.I placed the views.properties file in the classpath of my project to render the view in pdf format.The below lines of code i am using in the views.properties file.

packageWisePdfView.class=org.springframework.web.servlet.view.jasperreports.JasperReportsPdfView packageWisePdfView.url=/WEB-INF/packagewisereport1.jrxml

Where packageWisePdfView is my jsp name which is returned by the spring controller class.Using .class i am telling that render the pdf view.Using url i am telling where my jrxml is located.

Main thing is my packageWisePdfView.jsp is empty because i dont know what code i have to place over there.I am thinking that if i configure the view class in my views.properties file then it will automatically render the view to my packageWisePdfView.jsp.I dont know i am thinking in the correct way or not.But if i do like this i am getting the emptypage.Anything more i have to do.I am new to the jasper as well as spring also.Can any one help me regarding this.Please.....

Below is my controller class code:

public ModelAndView addTemplate(@ModelAttribute("reports") RaReports model, HttpServletRequest request,HttpServletResponse response) throws Exception {

String pdfFile =request.getSession().getServletContext().getRealPath("/") +"packagewisereport.pdf";

String jasperFile = request.getSession().getServletContext().getRealPath("/") + "packagewisereport1.jrxml";

JasperDesign jasperDesign = JRXmlLoader.load(new File(jasperFile));

JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

JasperPrint print = JasperFillManager.fillReport(jasperReport, map, conn);

JRPdfExporter jrPdfExporter = new JRPdfExporter();

jrPdfExporter.setParameter(JRExporterParameter.JASPER_PRINT,print);

jrPdfExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,pdfFile);

jrPdfExporter.exportReport();

return new ModelAndView("packageWisePdfView");

}

packageWisePdfView.jsp is empty i dont know what to write over there.Its very urgent to me can anyone please help me....

Thanks In Advance...
