HI,
Try out this code :
FileInputStream is = new FileInputStream(file);
      long length = file.length();
      byte[] bytes = new byte[(int)length];
      long bytesRead = is.read(bytes);
      if (bytesRead < length)
       throw new IOException("Could not completely read file "+file.getName());
      is.close();
element.setDocumentContent(bytes);
Create a context attribute of binary type and assign the read data to it and bind the dataSource property of your File Upload and Download properties to this context Attribute.
