 We it do as following:
    ServletOutputStream out = null;
    
   HttpServletResponse response =    FacesUtils.getServletResponse();
    
   response.setContentType("application/pdf"); 
    
   byte[] bytes    = // read you PDF from file here
    
   response.setContentLength(bytes.length);
    
   try    {
       out =    response.getOutputStream();
          out.write(bytes, 0, bytes.length);
   } catch    (IOException ex) {
   } finally    {
       try    {
              out.flush();
              out.close();
   } catch    (IOException ex) {       }
   }
    
   facesContext.responseComplete();
  
 Regards,
 Stan.

Subject: A question about  showing/opening PDF-file in run-time


 
 Good day  everybody,

My code look as follow. What I want to do is: I  generate a pdf-file in 
run-time and put it under a dir in server-side, assumed  under 
"c:\temp\myfile.pdf". If one clicks the commmanlink, the PDF-file will be  
opened in a new browser window with tool-bar which contains save, print  etc.
  
 My code look as follow. And I want to know how can I write the  function 
showPDF() in my backing bean. 

Or one can do this in an other  way?

Thanks

Thomas
