Display blob field image in Oracle Express

Question

Hi,
I upgraded the apex in my Oracle express edition to 3.2 and tried to display image in blob field following the step in the Apex tutorial,
but the error '*The requested operation is not allowed* ' prompt.
I save the image file in a table with fields mime1,picture1=> blob field.
I created a problem as follow:
CREATE OR REPLACE PROCEDURE download_my_file(p_hotel_id in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
--execute immediate
--'SELECT MIME_TYPE'||to_char(p_picture)||', picture'||to_char(p_picture)||', '||to_char(p_picture)||',DBMS_LOB.GETLENGTH(blob_content) '||
--'INTO v_mime,lob_loc,v_file_name,v_length FROM hotels_pic '||
--'WHERE hotel_id = '||to_char(p_hotel_id);
select mime_type1,picture1,'test/picture1',DBMS_LOB.GETLENGTH(picture1)
INTO v_mime,lob_loc,v_file_name,v_length
from hotels_pic where hotel_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
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;
GRANT EXECUTE ON download_my_file TO apex_PUBLIC_user;
GRANT EXECUTE ON download_my_file TO public;
I tried display the image by using <img src="#OWNER#.download_my_file?p_hotel_id=1" height=60 width=40 /img>
But the image don't display...
if I type http://127.0.0.1:8080/apex/HOTEL.download_my_file?p_hotel_id=1 to display the picture , the error " Forbidden,The requested operation is not allowed" prompt.
Am I miss out anything? Anyone can help?
Thanks

Hi,
I use a slightly difference code to display images: [http://apex.oracle.com/pls/otn/f?p=267:11]
It is possible that your GRANT command needs to be for PUBLIC instead of public - some things are case-sensitive.
Also, have you checked in SQL Workshop, Object Browser, Procedures to see if your procedure is valid?
