Below code is used to download the file . The content types and the header are changed manually(as of now for testing ) to match the file types .

public void downloadFile(FacesContext facesContext,

                                 OutputStream outputStream) {

            DCBindingContainer lBindingContainer =

(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();

            BlobDomain blob ;

            DCIteratorBinding lBinding = lBindingContainer.findIteratorBinding("<iterator name>");

             blob =

(BlobDomain)lBinding.getCurrentRow().getAttribute("FileAttach");

            String filename =

(String)lBinding.getCurrentRow().getAttribute("FileName");

            HttpServletResponse response = (HttpServletResponse)ectx.getResponse();

            response.setContentType("docx");

response.setHeader("Content-Disposition", "attachment;filename=\"" + fileName + ".docx"+ "\"");

            try {

System.out.println("blob.getLength()" + blob.getLength());

                OutputStream os = response.getOutputStream() ;

System.out.println("blob.getCharacterOutputStream()" + blob.getCharacterStream());     

System.out.println("filename" + filename);       

                //copyStream(blob.getInputStream(), outputStream);

copyStream(blob.getInputStream(), os);

System.out.println("os" + os.toString());       

             //   blob.closeInputStream();

                //outputStream.flush();

            } catch (IOException e) {

                e.printStackTrace();

            }

            finally {

                    try {

                        outputStream.flush();

                        outputStream.close();

                    } catch (IOException e) {

                        e.printStackTrace();

                    }

            }

        }

Could someone help me in resolving this issue .
