Question

Hi all,
I have created a procedure to download a file.
the name of the procedure is download_my_file4
create or replace PROCEDURE download_my_file4(p_file in number) AS
        v_mime  VARCHAR2(48);
        v_length  NUMBER;
        v_file_name VARCHAR2(2000);
        Lob_loc  BLOB;
        a NUMBER;
BEGIN
     select s.siteid into a from site s,lbconline_users c where
           c.user_lbc_site=s.siteid and lower(c.user_login)=lower(v('APP_USER'));
    for c in (select a.siteid site, b.con_id conid from kconts a, con_doc_info b where a.con_id = b.con_id )
     loop
      IF  c.site = a  THEN
        SELECT MIME_TYPE, BLOB_CONTENT,NAME,DBMS_LOB.GETLENGTH(blob_content)
                INTO v_mime,lob_loc,v_file_name,v_length
                FROM CON_DOC_INFO
                WHERE id = p_file and con_id = c.conid;
        owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
        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 if;
    end loop;
end download_my_file4;Permission has been granted to public
when i use this procedure in the report like
#owner#.download_my_file4?p_file=#File No.#
it is giving the error:
404 not found
The requested URL /pls/htmldb/INFOCENTRE.DOWNLOAD_MY_FILE4 was not found on this server.
Any help please?
Thanks in advance

If you want to call packages procedures from the URL, you need to add it to a security function in the FLOWS schema:
# You need to make this procedure callable, so go to the FLOWS030100 schema
# Go to the Function WWV_FLOW_EPG_INCLUDE_MOD_LOCAL
# Add the "INFOCENTRE.DOWNLOAD_MY_FILE4" to the code like this:
if upper(procedure_name) in ( 
  'ADD_AS_A_FRIEND', 'INFOCENTRE.DOWNLOAD_MY_FILE4') then    
   return TRUE; 
else   
   return FALSE; 
end if;  Now you procedure is callable from the URL!
