FM for converting PDF to XSTRING - display R/3 report in Portal as PDF

Question

Hello SDNers,
Requirement:
I am trying to display an R/3 report in Portal as PDF. I am trying to do it with the following logic:
1. Call a RFC enabled FM from my Webdynpro Java appln.
2. The FM then submits the Print request for the R/3 report and then gets the spool.
3. Convert the ABAP spool to PDF (using FM CONVERT_ABAPSPOOLJOB_2_PDF).
4. Convert the PDF to XSTRING and send it back to the calling Webdynpro appln.
5. Using the XSTRING regenerate the PDF using some Webdynpro Java APIs.
The Problem / Question:
The output of the FM CONVERT_ABAPSPOOLJOB_2_PDF is a table of type "TLINE" which includes TDFORMAT and TDLINE.
To get the XSTRING I am using the FM "'SCMS_STRING_TO_XSTRING". This FM only uses the "TDLINE" and completely ignores the "TDFORMAT". When I import this XSTRING value into my Webdynpro for Java appln., and assign to the corresponding UI element, my PDF does not show up.
My FM code is like this:
CALL FUNCTION 'CONVERT_ABAPSPOOLJOB_2_PDF'
      EXPORTING
        src_spoolid                    = gd_spono
        no_dialog                      = 'X'
TABLES
   pdf                            = t_pdf
IF sy-subrc  0.
ENDIF.
IF sy-subrc EQ 0.
      LOOP AT t_pdf INTO w_pdf.
        CONCATENATE
          output
          w_pdf-tdformat
          w_pdf-tdline
        INTO output.
      ENDLOOP.
      CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
        EXPORTING
          text   = output
        IMPORTING
          buffer = outputx.
I doubt if "'SCMS_STRING_TO_XSTRING'" is the right FM to use in my scenario.
If we had a smartform, we could have used the FM "CONVERT_OTF" , but in our case we do not have a smart form and I am not able to figure out which FM should be used.
Please suggest if I am doing any thing wrong.
Thanks for Reading.

Hi
check this thread
spool to pdf conversion
It looks like you are missing translate in you processing of the table t_pdf. Something like the following line is missing:
TRANSLATE gd_buffer USING '~ '.
Loo at the standard program RSTXPDFT4 as well. It converts spool to PDF and then you can download it to your desktop.
