How to display blob (pdf) from database in static content region

GosforthFeb 10 2020 — edited Feb 11 2020

I have procedure:

create or replace PROCEDURE download_pdf_file(p_file in number) AS

        v_mime  VARCHAR2(48);

        v_length  NUMBER;

        v_file_name VARCHAR2(2000);

        Lob_loc  BLOB;

BEGIN

        SELECT file_ID, file_blob,DBMS_LOB.GETLENGTH(file_blob)

                INTO v_file_name,Lob_loc,v_length

                FROM pdf_files

                WHERE file_id = 1;

              --

              -- set up HTTP header

              --

                    -- use an NVL around the mime type and

                    -- if it is a null set it to application/octect

                    -- application/octect may launch a download window from windows

                htp.flush();

                htp.init();

                owa_util.mime_header( nvl('application/pdf','application/octet'), FALSE );

                -- set the size so the browser knows how much to download

                htp.p('Content-length: ' || v_length);

                -- the filename will be used by the browser if the users does a save as

                htp.p('Content-Disposition:  inline; filename="some_file.pdf"');

                -- close the headers           

                owa_util.http_header_close;

                -- download the BLOB

                wpg_docload.download_file( Lob_loc );

end download_pdf_file;

If I try this procedure:

begin

download_pdf_file(1);

end;

It gives me output (content of pdf file)

So I create test page with static content region. I put there source:

<embed src="#YUJK#.download_pdf_file?p_file=1" width="500" height="375">

And nothing.

Anyway, it can be anything.. like #asdfg#.dfgdfgdfgd?p_file=1" for Apext this is OK. So looks like this is the problem - how to check if APEX really gets this link?
