Problem After writing the Jfree chart into pdf

Question

Hi All,
I am writing the Jfreechart object with my company logo into JSP and and setting the content type as "application/pdf". I am getting the error as
java.lang.IllegalStateException: getOutputStream() has already been called for this response.
I have searched for it in the google as well as sun forums for so many hours and i implements so many suggested solutions but i am unable to remove the exception.
The problem might be using response.getOutputStream() to get the output stream to in the response.
But while debugging the code I observed that I am getting the error after complete execution of the code ie. after displaying the pdf.
I am using JSF with JBoss portlets.
Could any one help me in solving this problem as soon as possible..
Thanks in advance.

I am using the fallowing code to write into response. After execution of all the code and after displaying pdf its throughing the exception
*OutputStream outStream = response.getOutputStream()*
//To get the logo path from propeties file
ResourceBundle resourceBundle = ResourceBundle.getBundle("imagepath");
                  String imagePath = resourceBundle.getString("imagepath");
                  Image image2 = Image.getInstance(imagePath);
                    image2.scaleToFit(100, 100);
                    PdfPTable pdfPTable =  new PdfPTable(2);
                    pdfPTable.getDefaultCell().setBorder(0);
                    PdfPCell cell = new PdfPCell(image2);
                    cell.setHorizontalAlignment(Element.ALIGN_LEFT);
                    cell.setBorder(0);
                    pdfPTable.addCell(cell);
                    pdfPTable.addCell("");
                  //get the Pdf writer object
               PdfWriter     writer = PdfWriter.getInstance(document, outStream);
                   document.open();
               document.add(pdfPTable);
                  PdfContentByte contentByte = writer.getDirectContent();
                  PdfTemplate template = contentByte.createTemplate(1200, 750);
                  Graphics2D graphics2d = template.createGraphics(600, 750, new DefaultFontMapper());
                  Rectangle2D rectangle2d = new Rectangle2D.Double(0, 0, 540, 700);
                  jfreechart.draw(graphics2d, rectangle2d);
                  graphics2d.dispose();
                  contentByte.addTemplate(template, 50, 25);
                  //setOldchartObject(chartInfoBean);
                  System.out.println("This is before closing th edocument.");
                  document.close();
