try {
        Document document = new Document();
        PdfWriter.getInstance(document, new FileOutputStream("FicheClient.pdf"));
        document.open();
        document.add(new Paragraph("hello World",FontFactory.getFont(FontFactory.TIMES_BOLD,20,Font.BOLD,BaseColor.BLACK)));
        document.add(new Paragraph("---------------------------------------"));
        document.close();
        JOptionPane.showMessageDialog(null, "Raport saved ");
    } catch (Exception e) {
    }
