Download doc problem when copied from APEX_APPLICATION_FILES to local table

Question

Good morning!
As the subject indicatesm, I am experiencing problems downloading a document I have copied from APEX_APPLICATION_FILES to my local table FILE_SUBJECTS
and would be very grateful if someone could help.
Here is the problem:
I can successfully upload a document into APEX_APPLICATION_FILES and dowload it from there too.
I can copy the record from APEX_APPLICATION_FILES into my local table FILE_SUBJECTS and delete that entry from APEX_APPLICATION_FILES but I cannot download it from my local table, it keeps pointing me to a page which cannot be found, so I'm guessing there is something wrong with either, my INSERT INTO statement or, my link in the report.
My INSERT INTO statement is:
INSERT INTO file_subjects (id,filename,updated_by,updated_on,blob_content,mime_type)
SELECT id, filename, name, updated_by, updated_on,blob_content,mime_type
FROM APEX_APPLICATION_FILES
WHERE APEX_APPLICATION_FILES.filename = :P2_FILE_NAME;
REPORT LINK
I have tried just a normal column link in my report like: #ID# (this works when looking at APEX_APPLICATION_FILES)
but I have also tried the following:
#OWNER#.DOWNLOAD_MY_FILE?p_file=#ID#
where download_my_file is a procedure:
create or replace PROCEDURE "DOWNLOAD_MY_FILE" (p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
--apex_application.g_flow_id := 166;
--if not(APEX_CUSTOM_AUTH.IS_SESSION_VALID) then
-- owa_util.status_line(404, 'Page Not Found', true);
-- return;
--end if;
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM FILE_SUBJECTS
WHERE id = p_file;
-- 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
owa_util.mime_header( nvl(v_mime,'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: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end DOWNLOAD_MY_FILE;
Many thanks in advance!

Sue,
If you are running XE or running with the EPG versus the http server, you need to grant access to the procedure you are using for it to be run properly..
You may need to look at this function, if you are using XE or have the EPG setup for your database.. http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e12856/adm_wrkspc.htm#BABEFDHI [Look for the section called *Restricting Access to Oracle Application Express by Database Access Descriptor (DAD)*]
