Howto return a pdf file as a stream?

I was just wondering how do I return a PDF file as a stream as my response using
jsf/myfaces?

So I can just copy my method from an Struts application I have and apply it here,
just instead of returning null I just call context.responseComplete(); at the end?

This line is the key.  

Make sure you are able to return a PDF as a servlet or something first
just to make sure you have everything figured out (assuming you are
new to writing PDF.)  Then try with faces.

Hi Bjorn,

here is just the way how we did it:

public void print(ActionEvent event) {
    FacesContext context = FacesContext.getCurrentInstance();
    HttpServletResponse response =
      (HttpServletResponse) context.getExternalContext().getResponse();

    response.setContentType("application/pdf");
    FpRegisterableEJB bean = null;
    try {
      bean = createEquipedBean( getLink() );
      JCPrinter printer = PrintManager.getPDFPrinter( 
response.getOutputStream() );
      PrintManager.printDocument( getReport( printer , bean ) , printer );
    } catch (Exception e) {
      logAndRethrowException( e );
    } finally{
      removeBean(bean);
    }
    context.responseComplete();
  }


regards

Rico
