Problems with OWA_COOKIE send and get

Question

Hi all,
I have a problem with OWA_COOKIE-package. What I'm trying to do is to integrate Oracle eBS and an APEX app. The application resides on different databases and servers.
I'm basing my code on this white paper:
http://www.oracle.com/technology/products/database/application_express/pdf/Extend_Oracle_Applications_11i.pdf
I have the function set up in eBS and it redirects me to my APEX login page. The next step is to pass a cookie with the user name password to the APEX app. Here the problems begins.
My launch code in the eBS database (lots of hardcoded values just for the test):
PROCEDURE xxapex_launch (application IN NUMBER DEFAULT 107
                       , page IN NUMBER DEFAULT 1
                       , request IN VARCHAR2 DEFAULT null
                       , item_names IN VARCHAR2 DEFAULT NULL
                       , item_values IN VARCHAR2 DEFAULT NULL) AS
BEGIN
  OWA_UTIL.mime_header('text/html', false);
  OWA_COOKIE.send (name => 'APEX_APPS_107',
                   value => 'daniel:development',
                   expires => sysdate + 365,
                   path=>'/');
  OWA_UTIL.redirect_url('http://server:8090'||'/apex/f?p='||
                        application||':'||page||'::'||request||':::'||
                        item_names||':'||item_values);                       
END xxapex_launch;
The application process in APEX that should read the cookie(on-load before header):
DECLARE
  c OWA_COOKIE.cookie;
  a wwv_flow_global.vc_arr2;
BEGIN
  c := OWA_COOKIE.get('APEX_APPS_107');
  a := htmldb_util.string_to_table(c.vals(1));
  :P160_USERNAME := a(1);
  :P160_PASSWORD := a(2);
  IF :P160_PASSWORD IS NOT NULL THEN
    wwv_flow_custom_auth_std.login(
       P_UNAME => :P160_USERNAME,
       P_PASSWORD => :P160_PASSWORD,
       P_SESSION_ID => v('APP_SESSION'),
       P_FLOW_PAGE => :APP_ID||':160');
__END IF;
END;The error I get is no-data-found when this is run:
:P160_USERNAME := a(1);
The c.num_vals is 0 and what I can understand OWA_COOKIE.get does not find my cookie. Is there anybody out there that can point on what I'm doing wrong?

Back on this....
Is there somebody that have successfully implemented the solution described in?
http://www.oracle.com/technology/products/database/application_express/pdf/Extend_Oracle_Applications_11i.pdf
Questions:
Should I create a custom login page or use the default (that using my custom Authentication Scheme)?
In the white paper where it's described on how to create the application process (that reads the cookie) it says (page 5):
"This process should be conditional and should not be run if the login page is processing a logout request."
Does somebody know on how to achive this?
In my case my eBS is on one server and the APEX installation is on another server, I don't know if that's
what preventing it to work.
I'm trying to make a very simple proof of conecpt, my app only contain one login page (the default) and
one blank HTML-page. I have a database link between my APEX and EBS database (using APPS user). My
app works fine in a stand-alone scenario. But when I start it from EBS I get the login page (the appl.
process code has not fired) and if I tries to login using a username and a pwd I can se that the
appl. process fires and is reading the cookie correctly. The problem is that it "hangs" and it seems that
appl. process fires over and over again (can see that in my log table).
My code:
The Authentication Function
create or replace FUNCTION demo_ebiz_suite_auth
(p_username in VARCHAR2,
p_password in VARCHAR2) return BOOLEAN is
begin
__return true; /* can log in with whatever */
end;
Application Process - On load: Before header (page template header)
DECLARE
__c OWA_COOKIE.cookie;
__a wwv_flow_global.vc_arr2;
BEGIN
__demo_toLog('APEX process', '1');
__c := OWA_COOKIE.get('APEX_APPS_'||:APP_ID);
__a := htmldb_util.string_to_table(c.vals(1));
__:P101_USERNAME := a(1);
__:P101_PASSWORD := a(2);
__demo_toLog('APEX process', ':P101_USERNAME '||:P101_USERNAME);
__demo_toLog('APEX process', ':P101_PASSWORD '||:P101_PASSWORD);
__demo_toLog('APEX process', ':APP_ID '||:APP_ID);
__IF :P101_PASSWORD IS NOT NULL THEN
____demo_toLog('APEX process', 'before trying to login');
____wwv_flow_custom_auth_std.login(
______P_UNAME => :P101_USERNAME,
______P_PASSWORD => :P101_PASSWORD,
______P_SESSION_ID => v('APP_SESSION'),
______P_FLOW_PAGE => :APP_ID||':1'
____demo_toLog('APEX process', 'after login');
__END IF;
EXCEPTION
__WHEN OTHERS THEN
____demo_toLog('APEX process', 'Fel: '||SQLERRM);
END;
Maybe I'm doing some simple misstake here but I can't see it. I need a second opinion.
Thanks.
