In the Oracle Identity Management Suite Integration with Oracle Utilities Application Framework based products (Doc Id: 1375600.1) whitepaper the Oracle Access Manager integration section mentions a custom landing page that can be used to complete the integration.
A sample landing page is now available from My Oracle Support for customers to use as a basis for their own landing pages. It is located within My Oracle Support under Sample Code oamlanding.jsp - refer to the Instructions in Note 1375600.1 (Doc Id 1518856.1).
This is a sample only and should be tested and modified to suit your individual site needs. Refer to Doc Id 1375600.1 for instructions on how to use the landing page.
