I haven't worked with portals before, so I can't help you on that. But I do have a question - why are you trying to integrate them in the first place?? Have you or somebody already purchased them separately and you're stuck trying to integrate them? JavaPro magazine's May 2002 issue has the reader's choice awards, and Weblogic Portal Server was #1 portal, with iPlanet not even on the map.
