How to show a PDF with a JSF jsp.

Question

Hello,
I want to show a PDF in a JSF jsp.
I'm a newbie with this, and don't know where to look for information about that.
Any example on the web ?
Thanks in advance

I think you will need to eventually get it to the HTML <object> tag anyway.
<OBJECT data="yourPDFhere.pdf" type="????""/>
and to get the byte[] to the client you may need to make a Servlet to respond to *.pdf requests and feed the correct session 'in memory' pdf out the stream.
Here is an example from some svg 'in memory' per session I was testing:
* SessionServlet.java
* Created on June 3, 2004, 12:09 AM
package com.hypernex.xml.svg;
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
* @author  Roger I Martin, PhD
* @version
public class SessionServlet extends HttpServlet
    /** Initializes the servlet.
    public void init(ServletConfig config) throws ServletException
        super.init(config);
    /** Destroys the servlet.
    public void destroy()
    /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException
        ServletContext context=getServletContext();
        java.util.Enumeration e=context.getServlets();
        while(e.hasMoreElements())
            System.out.println("servlets \t"+e.nextElement());
        /*e=context.getAttributeNames();
        while(e.hasMoreElements())
            System.out.println("AttributeNames \t"+e.nextElement());
        e=request.getParameterNames();
        while(e.hasMoreElements())
            System.out.println("ParameterNames \t"+e.nextElement());
        System.out.println("getContextPath "+request.getContextPath());
        System.out.println("getRequestURI"+request.getRequestURI());
        response.setContentType("text/xml+svg");
        PrintWriter out = response.getWriter();
        HttpSession httpSession=request.getSession();
        System.out.println("getQueryString"+httpSession);
        if(httpSession!=null && request.getRequestURI().endsWith("wafermap.svg"))
            /*e=httpSession.getAttributeNames();
            while(e.hasMoreElements())
                System.out.println("httpSession AttributeNames \t"+e.nextElement());
            SVGProducer svgProducer=(SVGProducer)httpSession.getAttribute("waferMap");
            out.print(svgProducer.getSVGView());
        else if(httpSession!=null && request.getRequestURI().endsWith("hardware.svg"))
            SVGProducer svgProducer=(SVGProducer)httpSession.getAttribute("hardwareBean");
            out.print(svgProducer.getSVGView());
        else if(httpSession!=null && request.getRequestURI().endsWith("geometry.svg"))
            SVGProducer svgProducer=(SVGProducer)httpSession.getAttribute("geometryBean");
            out.print(svgProducer.getSVGView());
        else
            try
                java.io.BufferedReader br=new java.io.BufferedReader(new java.io.FileReader("./webapps"+request.getRequestURI()));
                String line=null;
                while((line=br.readLine())!=null)
                    out.println(line);
                br.close();
            catch(java.io.IOException ioe)
                System.out.println("ioe:"+ioe.getMessage());
        out.close();
    /** Handles the HTTP <code>GET</code> method.
     * @param request servlet request
     * @param response servlet response
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException
        processRequest(request, response);
    /** Handles the HTTP <code>POST</code> method.
     * @param request servlet request
     * @param response servlet response
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException
        processRequest(request, response);
    /** Returns a short description of the servlet.
    public String getServletInfo()
        return "SVG graphics handler";
