Configuration of Single Sign On (SSO) from SAP CE 7.01 Portal to Oracle E-Business Suite

Hi Team,

Can anybody help me for the below requirement:

 Requirement : Configuration of Single Sign On (SSO) from SAP CE 7.01 Portal to Oracle E-Business Suite 12.1.1 which is having a Web user interface (UI).

i have checked the SAP Help portal (http://help.sap.com/saphelp_nw70/helpdata/En/f8/9636eedafe8b4589cd6e9e4e73fd3c/frameset.htm)

Here have given 3 methods to establish SSO to External systems.

   1. Dynamic Link Library SAPSSOEXT
   **  Use this library to enable SSO to Java and C applications programmatically.

        2.Web Server Filter (Possibility for implementing this method)
**  Use this filter to enable Single Sign-On (SSO) with logon tickets to Web applications that support authentication with an HTTP header variable.

    3.Web Server Filter with Delegation for Windows Server 2003
   **Use this filter to enable SSO to a Microsoft Web-based application.
