APEX

I'm trying to configure SSO on APEX and have followed the steps listed in the How-To doc "Configure an Application Express Application as a Partner Application in Oracle AS Single Sign-On" found at

http://www.oracle.com/technetwork/testcontent/sso-partner-app-100552.html

I am using the following versions:

Oracle DB 11.2.0.1.0
APEX 4.0.2.00.07
SSO SDK 9.0.2
Embedded PL SQL Gateway in DB

Here are the steps I followed to install the WWV_FLOW_CUSTOM_AUTH_SSO package:
-----

SQL> create synonym wwsec_enabler_config_info$ for apex_sso.wwsec_enabler_config_info$;

Synonym created.

SQL> create synonym wwsec_sso_enabler_private for apex_sso.wwsec_sso_enabler_private;

Synonym created.

SQL> @custom_auth_sso_902.sql
...wwv_flow_custom_auth_sso

Package created.

No errors.
SQL> start custom_auth_sso_902.plb
...wwv_flow_custom_auth_sso

Package body created.

No errors.
SQL> grant execute on wwv_flow_custom_auth_sso to APEX_PUBLIC_USER;

Grant succeeded.

SQL> alter package WWV_FLOW_CUSTOM_AUTH_SSO compile body;

Package body altered.

-----

I also created the public synonym for wwv_flow_custom_auth_sso as follows:

SQL> create public synonym WWV_FLOW_CUSTOM_AUTH_SSO for APEX_040000.WWV_FLOW_CUSTOM_AUTH_SSO;

Synonym created.


SYNONYM_NAME ==> WWV_FLOW_CUSTOM_AUTH_SSO
OWNER =======> PUBLIC
TABLE_OWNER ===> APEX_040000
TABLE_NAME ====> WWV_FLOW_CUSTOM_AUTH_SSO

-----

There were no errors while following all steps in the How-To doc, and I am correctly redirected to the SSO login page when I access my app. But after a successful SSO validation, I receive this 404 Error message:

---- Not found
---- The requested URL /apex/wwv_flow_custom_auth_sso.process_success was not found on this server

I have seen a few other posts with the same or similar symptoms, but I haven't seen any that have been resolved yet.

Please let me know if you see something I'm missing or have any suggestions.

Thanks,

Troy
