RESTful API - Can't Get Filename when POSTing?

Hi,

I've been trying to do an upload using a jquery Mutliple File upload directly through the APEX Listener so I can then be able to save the files as BLOB.  I'm able to do so, but the issue that I have is that I can't retrieve the "filename".

Here is the info of my URI template:

Method: POST

Source Type: PL/SQL

Requires Secure ACcess: No

Source:

declare

   l_id number;

begin

   insert into table1 (mime, binary, filename) values (:contentType, :body, :my_file) returning id into l_id;

   commit;

end;

Parameters:

(Name, Bind Variable Name, Access Method, Source Type, Parameter Type)

filename, my_file, IN, HTTP Header, String

The value in :my_file is always null. Does someone know why?

If I can't get the exact filename, my guess would be to take the content disposition and parse it for 'filename="my_file.txt"', but when I try to use "Content-Disposition" as a parameter, I get null as well.

I'm using APEX 4.2 with 11g. This is the info on my server:

X-Powered-By: Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 3.1.2.2 Java/Oracle Corporation/1.7)

Server: Oracle-Application-Express-Listener/2.0.3.221.10.13

Thanks!
