How to show in a report a pdf blob from database

Question

Hi all
We are working on report 6i and report 10. We have a report wich needs to show a blob field from database that storages a pdf (type application/pdf). OLE2 is deprecated. The pdf blob field must be displayed in a preview and must be printed. In local, it works. When it works on a browser, the pdf blob field is missing. If we load the field into a pdf file, the field is not visible in the browser.
Do not get it to work. How I can implement? Could you give us any example for this?

Answer 1

In local, it works. What do you mean by that exactly? You see the pdf in Reports Builder?
If you just want to show the pdf in a browser (not embedded in a report) it is easy to use mod_plsql. You can have a simple db procedure like this to show any kind of blob:
procedure show_webdoc(io_blob    in out nocopy blob
                     ,i_mimetype in varchar2
                     ,i_filename in varchar2)
is
begin
   if dbms_lob.getlength(io_blob) >0 then
      owa_util.mime_header(nvl(i_mimetype,'application/octet'),false);
      htp.p('Content-length: ' || dbms_lob.getlength(io_blob));
      htp.p('Content-Disposition:  inline; filename="'||i_filename|| '"');
      owa_util.http_header_close;
      wpg_docload.download_file(io_blob);
   end if;
end show_webdoc;
