JSf with Jasper Report sample example

Question

I am new to JSF and JasperReports. Can anyone suggest a sample webapplication for JSF with JasperReports which doesn't use a database connection?

You need to generate pdf from jasper report here are the samples for the same

Here is the code from BalusC blog for rendering PDF in JSF.
If you are using RichFaces then go for a4j:mediaOutput This will load PDF using AJAX.

Sample snippet to create PDF.

String fileName = "C:\\JasperReports\\report.jasper";
        UUID uu = new UUID(3, 4);

        String outFileName =  "C:\\TempReport\\" + uu.randomUUID().toString() + ".pdf";

        hm.put("year", new Integer(y).toString());
        hm.put("timezone", sTimezone);

try {
            JasperPrint print = JasperFillManager.fillReport(
                    fileName,
                    hm,
                    new JREmptyDataSource());
            JRExporter exporter =
            new net.sf.jasperreports.engine.export.JRPdfExporter();
            exporter.setParameter(
            JRExporterParameter.OUTPUT_FILE_NAME,
            outFileName);
            exporter.setParameter(
            JRExporterParameter.JASPER_PRINT, print);
            JasperExportManager.exportReportToPdfFile(print, outFileName);
            print = null;
            exporter = null;
            JasperViewer.viewReport(print,false);
        } catch (Exception e) {
            e.printStackTrace();
        }
