HOW TO SEND XML BACK TO PRINT? (See Inside thread for more info)

Question

Hello Everybody,
Because there is not a lot of documentation on  if_fp and if_fp_pdf_object
I found out that i can retrive my PDF from the ADS with the following code:
    data:
    lo_fp                 TYPE REF TO if_fp ,
    lo_pdfobj             TYPE REF TO if_fp_pdf_object,
pdf_xstring           TYPE xstring,
    xml_data              TYPE xstring,
    lv_xml_data_string    TYPE string.
            Get FP reference
  lo_fp = cl_fp=>get_reference( ).
            Create PDF Object using destination 'ADS' (<-- this is how it is defined in SM59)
  lo_pdfobj = lo_fp->create_pdf_object( connection = 'ADS' ).
            set document
  lo_pdfobj->set_document(
  EXPORTING
    pdfdata = fp_formoutput-pdf ). " fp_formoutput-pdf is of type xstring
            Tell PDF object to extract data
lo_pdfobj->set_extractdata( )." obsolate!!!
  call METHOD lo_pdfobj->set_task_extractdata( ).
            Execute the call to ADS
  lo_pdfobj->execute( ).
  lo_pdfobj->get_data(
  IMPORTING
    formdata = xml_data ).
After this i can manipulate xml_data but dont know how to send it back to print...
Can you direct me to the solution please?
Thank you in advance,
Eran Fox

Hi Billy
Yikes - how embarassing !  Thanks for pointing out my beginners mistake there.  I've fixed my code - and also implemented the substitutions of parameters like you suggested - I like that approach.
Unfortunately the end result is no better - the line
utl_http.read_text(resp,response_text);
Still returns nothing back
The headers that are coming back are
Date: Thu, 04 Jul 2013 08:31:56 GMT
Server: Apache/2.2.16 (Ubuntu)
X-Powered-By: PHP/5.3.3-1ubuntu9.3
Expires: Thu, 19 Nov 1981 08:52:00 GMT

Connection: close
I guess I will need to try chasing it with the fastsms vendor so see if they can check my incoming request and see if there are any glaring problems. I know the xml is correct as I am now logging the xml string just before I send it and when I take that string and put it in their test form it works perfectly - something else in the puzzle is missing. I've had no experience using utl_http before - perhaps it's no possible to read the xml repsonse using this ?
Anyway, thanks for your help Billy.
ps - How do you paste your code into your message to get that formatting ?
Cheers,
Brent
