javax.servlet.http.HttpServletResponse,
com.lowagie.text.Document,

com.lowagie.text.rtf.RtfWriter" %>
%>


<%
 // we retrieve the presentationtype
    String presentationtype = request.getParameter("presentationtype");

    // step 1
    Document document = new Document();


    // step 2: we set the ContentType and create an instance of the
corresponding Writer
    response.setContentType("application/pdf");
    PdfWriter.getInstance(document, response.getOutputStream());


     // step 3
    document.open();

    // step 4
    document.add(new Paragraph("Hello World"));
    document.add(new Paragraph(new Date().toString()));
