How to display an SAP document on the web (ECC 6.0)

Question

Hello all,
  currently upgrading from 46C to ECC60 and we are having trouble with one of our current processes. 
We currently have a custom RFC that creates spool files and turns them into a PDF stream via CONVERT_OTFSPOOLJOB_2_PDF.  The RFC is called from one of our web applications that then displays the document via PDF on the web.
We are having trouble using this same process in ECC 6.0 so I'm wondering if there is a different approach to do this in ECC 6.0.
History of what has been done so far.
1) since we are now on a UNICODE system the PDF stream sent via the RFC call was displaying chinese characters instead of "%PDF" etc (2hex char vs 4hex char). We attempted to fix this by using the method cl_abap_conv_in_ce=>create to convert each line of the PDF stream.
2) After inserting the method some of the documents started working but others are getting a parsing error.
We are looking to see if anyone knows of a more standard approach to getting the same thing done.

Answer 1

We have experienced the same problem since we upgraded to ECC 6 and unicode last week.  The suggested code worked but there was a step missing in the example that I would like to share.
The spool output was table TLINE which is 134 characters.  Once you convert to non-unicode you actually have to put the results in a 268 char table.  When you read it in .NET and convert it to a binary array before passing it to Acrobat for viewing you have to make sure that you pad each record with spaces up to 268 charactes.  This was key!
Here is the code from our RFC after calling the CONVERT_OTFSPOOLJOB_2_PDF with a spool id:
data: PDF STRUCTURE  ZC268_STRUCT occurs 0 with header line.
call function 'CONVERT_OTFSPOOLJOB_2_PDF'
  exporting
    src_spoolid                    = f_rqident
  tables
    pdf                            = pdf.
data:     rf_conv type ref to cl_abap_conv_in_ce.
rf_conv = cl_abap_conv_in_ce=>create( encoding = 'NON-UNICODE' ).
data: fta_data type table of zc268_struct with header line.
data: f_str    type string.
field-symbols: <f_src> type x.
loop at pdf assigning <f_src> casting.
     call method rf_conv->convert(
      exporting input = <f_src>
      importing data  = f_str ).
      fta_data        = f_str.
      append            fta_data.
      clear             fta_data.
endloop.
The data in fta_data can be passed to .NET
I hope that helps.
