Problem with uploading files in 11g

Question

I upgraded the pre-installed APEX 3.0 in Oracle 11g to version 3.2. I created a form to upload files to the table htmldb_application_files and then copy the transaction to my custom table. However, after I "saved" the transaction, nothing happened. No file was uploaded into the htmldb_application_files table. Also, the "save" process took a while to finish.
I used to do this in my other applications in Oracle 10g and everything worked fine. Is it an issue with Oracle 11g?
Thanks.

Answer 1

I think I just did something wrong myself. I was finally able to upload the file. However, I wrote the following procedure in my package but wasn't able to download the file from the report. Do I need to grant any privilege from the system user?
Also, does anyone know how to convert a BLOB table into 11g Securefiles table?
Thanks.
<pre>
procedure download_birth_cert(p_vrds_birth_cert_pk in number) is
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(4000);
Lob_loc BLOB;
begin
select mime_type, blob_content, file_name, dbms_lob.getlength(blob_content)
into v_mime, lob_loc, v_file_name, v_length
from vrds_birth_cert
where vrds_birth_cert_pk = p_vrds_birth_cert_pk;
-- 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 user does a save as
htp.p('Content-Disposition: attachment; filename="'||substr(v_file_name,instr(v_file_name,'/')+1)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
exception
when others then
null;                    
end download_birth_cert;
