Problem with iReport and JSF

I'd like to show a report generated by iReport, in a JSF page. I use this method in my bean,

public void print () {
    try {
        Map<String, String> parameters = new HashMap<String, String>();
        parameters.put("ReportTitle", " My Title");
        List<monDto> listes = this.getList();

        JasperFillManager.fillReportToFile("C:/Reports/myreport.ja开发者_运维百科sper",
                                           parameters,
                                           new JRBeanCollectionDataSource(listes));

        JasperExportManager.exportReportToPdfFile("C:/Reports/myreport.jrprint");
    }
    catch (JRException e)
    {
        e.printStackTrace();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

Then in my XHTML page I declare a button using the print() method,

<h:commandButton  value="Click" action="#{myBean.print}" />

But when I clicked on the button, the method was not running.
