How to create PDF from . Jasper

Question

I created a report on iReports and managed . Jasper, but I have no idea how to generate the PDF, I’ve tried several tutorials and nothing works, to create the pdf. What I need is to generate the PDF and take the path of the file created to set within a field in the database. I was trying to use this method, does not return any error, but also does not create the file.

   public void imprimirRelatorio() throws IOException, ParseException {

        HashMap parametros = new HashMap();
        parametros.put("ID_EDITAL", 28);

        FacesContext facesContext = FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse) facesContext.getExternalContext().getResponse();

        response.setContentType("application/pdf");

        response.setHeader("Content-disposition",
                "inline; filename=\"arquivo.pdf\"");
        try {
            JRBeanCollectionDataSource dsColecao = new JRBeanCollectionDataSource(lista, false);
            JasperPrint impressoraJasper = JasperFillManager.fillReport("d:/Edital.jasper", parametros, dsColecao);
            ServletOutputStream streamDeSaida = response.getOutputStream();
            JasperExportManager.exportReportToPdfStream(impressoraJasper,
                    streamDeSaida);
        } catch (JRException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        facesContext.responseComplete();    
    }
}

Where I make the method call:

                    <p:commandButton value="Submit"
                        actionListener="#{editalBean.inserirEdital}" update="growl"
                        process="@this" />

When calling editalBean’s inserEdital method it calls the printRelatory method().

The list I pass on the datasource in this case is a list of Notices. Could someone help me? Give a direction? I’m totally lost.
