Convert tline into pdf file document in Java

[former_member397166]

Dear ALL,

     I built a RFC FM to convert smartform into tline which including PDF data.

the Code:

   Converting to PDF Format
  DATA l_lines TYPE TABLE OF tline WITH HEADER LINE.
*  DATA l_lines1 TYPE TABLE OF solix_tab WITH HEADER LINE.
  DATA l_docs TYPE TABLE OF docs.
  DATA len TYPE i.
  CALL FUNCTION 'CONVERT_OTF_2_PDF'
    IMPORTING
      bin_filesize           = len
    TABLES
      otf                    = job_output_info-otfdata[]
      doctab_archive         = l_docs[]
      lines                  = l_lines[]                          "this inner table include pdf file data
    EXCEPTIONS
      err_conv_not_possible? = 1
      err_otf_mc_noendmarker = 2
      OTHERS                 = 3.

  *CALL METHOD cl_gui_frontend_services=>gui_download
  *  EXPORTING
  *   bin_filesize = len
  *    filename     = 'c:\pdf.pdf'
  *    filetype     = 'BIN'
  *   CHANGING
  *    data_tab     = l_lines[]"i_objbin[]
  *  EXCEPTIONS
  *    OTHERS       = 1.

"If i want to save it in my PC ,call this FM CALL METHOD cl_gui_frontend_services=>gui_download.

But i dont want to do it.I want to pass the parameter l_lines[] to java(web) by RFC, and convert to pdf file and show in java(web).

thanks

Hi Freddy

In the RFC FM define a table parametr for these PDF lines and it will be returned when called via JAVA. then Java can use these lines to do display. What is the exact issue?

     How to use the lines to do display in Java?

     Is there a way to convert the PDF lines to XString in RFC FM and convert XString to PDF file in Java?

thanks

Hi,

I have not tested this.

But if I am not mistaken the 'CONVERT_OTF_2_PDF' output is PDF file hidden in a table.

If this is the case just set LINES as your output from the RFC function.

if you use servlet maybe you can even convert the table into something that can be sent using the

HttpServletResponse .

Regards.

Hi Freddy,

I am not sure why you use CONVERT_OTF_2_PDF which returns the PDF indeed in the CHAR-like table LINES.

Can you use CONVERT_OTF instead? CONVERT_OTF allows to return the PDF data in an XSTRING field BIN_FILE.

Best regards,

Alexander
