Integrating Oracle EBS and ApEx Aplication with Responsibilities and SSO.

Question

Good day all.
I am looking forward from getting somebody 's help, the trouble I am facing is described below:
a) I am currently working on SSO with EBS. I mean, my users can connect and work perfectly.
b) ApEx is Configured as Application Partner with SSO, and the application we built (it's call PR-Auto)
is working good under SSO platform. I mean I am able to login using TEST user and password TEST in
both applications (EBS and PR-Auto).
c) The thing is that I need to call PR-Auto from one responsibility in EBS;
Following my setup for the responsibility:
- I have created a function:
Name: APEX_FA_PR
Properties:
Function type: SSWA plsql
Web HTML :apps.apex_launcher.launch_fa_pr
Web Host agent: pls/apex
- I have created a menu, application and responsibility using the function APEX_FA_PR.
- I have create launcher package:
create or replace package apex_launcher is
procedure launch_fa_pr;
end apex_launcher;
create or replace package body apex_launcher as
procedure launch_fa_pr as
begin
/** 110 Is ID of PR-Auto, my app **/
/** 5 is my home page **/
f(p=>'110:5');
end;
end apex_launcher;
d) New responsibility shows on EBS menu page.
e) Click on responsibility, and the page shows 'redirecting to login server for authentication', but
nothing happens, page goes blank with this url:

the address of my application pr-auto is http://fahorromex37.fahorro.com.mx:8004/pls/apex/f?p=110
f) DBA teams follow instructions from the following documentation
"Integrating Oracle E-Business Suite Release 11i with Oracle Internet Directory and Oracle Single Sign-On"
and "Note 261914.1 Integrating Oracle E-Business Suite Release 11i with Oracle Internet Directory and
Oracle Single Sign-On"
g) We are using:
DB: Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production
SO: Linux 2.6.9-42.ELsmp
ApEx: 3.0.1.00.07
Any help will be greatly appreciated.

Answer 1

Many Thanks Daniel for your prompt reply.
Tried to understand the white Paper and your thread but I am still facing problem,although able to Call ApEX page but now i
want to pass th e session Id where I am stuck.
MY three functions:
CREATE OR REPLACE FUNCTION SYMAPEX.apex_authorise (
p_username IN VARCHAR2
, p_password IN VARCHAR2) RETURN BOOLEAN
AS
BEGIN
IF apex_validate_hash (p_username, p_password) THEN RETURN TRUE;
END IF;
RETURN (FND_WEB_SEC.validate_login@VCSDEV2_QA (p_username, p_password) = 'Y');
END apex_authorise;
CREATE OR REPLACE FUNCTION SYMAPEX.apex_generate_hash (
p_string IN VARCHAR2
, p_offset IN NUMBER DEFAULT 0) RETURN VARCHAR2
IS
BEGIN
IF p_string IS NULL THEN RETURN NULL;
END IF;
RETURN RAWTOHEX(UTL_RAW.cast_to_raw(
DBMS_OBFUSCATION_TOOLKIT.MD5(input_string=>p_string||':'||
TO_CHAR(SYSDATE-(p_offset/24*60*60),'YYYYMMDD HH24MISS'))));
END apex_generate_hash;
CREATE OR REPLACE FUNCTION SYMAPEX.apex_validate_hash (
p_string IN VARCHAR2
, p_hash IN VARCHAR2
, p_delay IN NUMBER DEFAULT 5) RETURN BOOLEAN
IS
BEGIN
FOR i IN 0..p_delay LOOP
IF p_hash = apex_generate_hash (p_string, i) THEN RETURN TRUE; END IF;
END LOOP;
RETURN FALSE;
END apex_validate_hash;
MY Launch Procedure:
CREATE OR REPLACE Package body OAE_PKG1 AS
PROCEDURE LaunchOAE1 (application IN NUMBER DEFAULT 101
, page IN NUMBER DEFAULT 111
, 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_'||application,
value=>FND_GLOBAL.user_name||':'||apex_generate_hash@QA_VCSDEV2(FND_GLOBAL.user_name),
domain => '.orvcsd01.symprod',
path=>'/');
OWA_UTIL.redirect_url('http://orvcsd01.symprod.com:7780'||'/pls/apex/f?p='||application||':'||page||'::'||request||':::'||ite
m_names||':'||item_values);
END LaunchOAE1;
END OAE_PKG1;
MY On Load before headre process:
DECLARE
c OWA_COOKIE.cookie;
a wwv_flow_global.vc_arr2;
BEGIN
c := OWA_COOKIE.get('APEX_APPS_101');
a := htmldb_util.string_to_table(c.vals(1));
:P111_USERNAME := a(1);
:P111_PASSWORD := a(2);
IF :P111_PASSWORD IS NOT NULL THEN
wwv_flow_custom_auth_std.login(
P_UNAME => :P111_USERNAME,
P_PASSWORD => :P111_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':111');
END IF;
END;
I am doing custom authencitaion and calling apex_authorise function there.
Although I am able to Call the ApEX and able to validate application server password,but moment i try taking help off cookies
to pass on my application session details to ApEX so that users would not have to login twice,i am gettign the error.
Second question:
Do we have any other methos of passing session to ApEX from Application server other than cookies.
Please suggest.
Thanks.
