OK, I am having a quick go at doing some Ajax interactions from browser to my portlet app. Everything looks good so far as long as I don't need access to session data (which will almost always be necessary). In my normal portlet usage I use request.getUserPrincipal() for userid and I will also need access to session info. When I map the calls directly to the web app via its URL it creates a new session and the userprincipal is null. Has anyone else experimented with something like this yet and can offer any pointers?
Thanks, Chris
