Anyone integrated SAP Enterprise Portal with a third party web content management system (e.g. Vignette)? I don't have too much exposure to SAP Portal, but I know it provides a J2EE App Server and there are something called iViews which I would assume are some sort of fancy JSPs and Servlets etc. Any insight will be helpful.
Iviews are component of a SAP Portal Page.
Such an Iview can be a SAP-kind-of-Servlet (DynPage or JSPDynPage), an URL, or part of the response of an URL (there are others type of iviews, such as webdynpro, SAP R/3 transaction, SAP BI request... but i don't think they will help you there). If you can integrate your CMS using JSP or URL, you're ok...
please see SAPHelp on the subject of portal component.
Note that there is also a KM system that can use/mount external resources (such as Documentum), but i don"t know much about this subject.
