Cannot export PDF File (Jasper reprting)

[Kasun Wixkramanayake]

public class Main {

    String reportSource = "./report/payment_report.jrxml";
    String reportDest = "./report/Hello.pdf";

    public static void main(String[] args) {


        Main m = new Main();
        try {
            m.add();
        } catch (JRException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }

    }

    public void add() throws JRException {
        Map<String, Object> param = new HashMap<String, Object>();

        JasperReport jr = JasperCompileManager.compileReport(reportSource);
        JasperPrint jp = JasperFillManager.fillReport(jr, param, new JREmptyDataSource());
        JasperExportManager.exportReportToPdfFile(jp, reportDest);
        JasperViewer.viewReport(jp);

    }
}

I used these jar files to run above code
jasperreports-4.0.2.jar
commons-digester-1.7.jar
commons-collections-3.2jar (commons-collections.jar)
commons-logging-1.0.4.jar
commons-beanutils.jar
iText-5.1.1.jar )
but i get following run time errors.

Moving to Java in General since this isn't a GUI related problem.
