Render HTML file within portal page

Question

I have uploaded an html file into a content folder as a file item type. I have a portal page with tabs and other content. I added a tab for this html file. I would like the user to click on the tab and have the html file rendered within the associated region.
Any ideas on how to do this?

G'day,
Heres a much cut down version of a package I built to do
just that, based on a posting by Jerry Silver some time ago.
(I used to do the URL thing but found it fidley and unstable --
it dies if you move folders around)
Enjoy

-- Provides the following procedures for displaying portal content:
-- html_file(P_FILE_ITEM_ID): display HTML content of the file "in place".
-- The idea of these procedures is that they can be called by custom type items.
-- NB: create the following as portal30
create or replace package display is
procedure html_file (p_folder_id           in number,
                              p_file_itemid           in number,
                              p_site_id                in number,
                              p_deref_image_paths in number default 0);
end display;
create or replace package body display is
| procedure html_file (p_folder_id in number, |
| p_file_itemid in number, |
| p_site_id in number) |
| |
| Prints the contents of the file type item identified by |
| P_FILE_ITEMID, P_FOLDER_ID, and P_SITE_ID to the browser via |
| calls to the HTP package. |
