SSO between SAP EP and JAVA app on WebSphere Application Server 5.1

Hi. I have 2 questions.

I am implementing SAP EP6 and need to display content from a WebSphere JAVA application inside the portal. The application is currently running on WAS 5.1.

1. Does anyone have any sample code or documentation regarding how to pass the SAP logon ticket to WebSphere JAVA application to accomplish SSO when inside the portal?

2. Does anyone have any sample code or documentation regarding how to pass the SAP logon ticket to WebSphere JAVA application to accomplish SSO when outside the SAP EP, but still within the same IE browser window where the SAP logon ticket exists?

Thanks for any feedback you could provide.
