Convert PDF to XSTRING and dysplay in portal(html)

Question

Hi experts :
  I need your help once again. I've read all the post regarding this issue but can't find a solution for my problem.
  Basically, I have to create a PDF from a spool, convert it to xstring and send it to the web via RFC.
  What I do is :
      Convert the spool to PDF using FM CONVERT_OTFSPOOLJOB_2_PDF.
      Convert the PDF tline table into XSTRING using a field symbol and a table of tlines (as described in one of the SDN blogs).
     Then, I send to the web the value reurned from the conversion of the PDF line to XSTRING.
   But, when opening the xstring there is nor PDF file but and error. If I download the PDF tline table, it works and can create the PDF, but nothing from the XSTRING.
   My questions are :
      Do we have to do any conversion on the portal side to convert the XSTRING into PDF?
      is there any possibility of downloading the xstring to my desktop in order to check if I could create the PDF file from it?.
Helpful answer will be rewarded.
Regards,
Carlos.

For the last question, use this code:
FORM write_bin_file
      USING
        i_filename      TYPE string
        i_file_xstring  TYPE xstring.
  TYPES xx(50) TYPE x.
  DATA lt_xstring TYPE TABLE OF xx.
  DATA l_length TYPE i.
  CALL METHOD cl_swf_utl_convert_xstring=>xstring_to_table
    EXPORTING
      i_stream = i_file_xstring
    IMPORTING
      e_table  = lt_xstring
    EXCEPTIONS
      OTHERS   = 3.
  l_length = XSTRLEN( i_file_xstring ).
  CALL METHOD cl_gui_frontend_services=>gui_download
    EXPORTING
      bin_filesize = l_length
      filename     = i_filename
      filetype     = 'BIN'
    CHANGING
      data_tab     = lt_xstring
    EXCEPTIONS
      OTHERS       = 3.
ENDFORM.                    "write_bin_file
