Thanx in advance...!:)

ConnectionManager con = new ConnectionManager();
    con.establishConnection();

    String fileName = "Pmc_Bill.jrxml";
    String outFileName = "OutputReport.pdf";
    HashMap params  = new HashMap();
    params.put("PName", pname);
    params.put("PSerial", psrl);
    params.put("PGender",pgen);
    params.put("PPhone",pph);
    params.put("PAge",page);
    params.put("PRefer",pref);
    params.put("PDateR",dateNow);
    try {

        JasperReport jasperReport = JasperCompileManager.compileReport(fileName);

        if(jasperReport != null )
           System.out.println("so far so good ");

        // Fill the report using an empty data source

        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, new JRTableModelDataSource(tbl.getModel()));//con.connection);
        try{
        JasperExportManager.exportReportToPdfFile(jasperPrint, outFileName);
        System.out.printf("File exported sucessfully");
        }catch(Exception e){
            e.printStackTrace();
        }
        JasperViewer.viewReport(jasperPrint);
    } catch (JRException e) {
        JOptionPane.showMessageDialog(null, e);
        e.printStackTrace();
        System.exit(1);
