Hi, it is a nice tip, but it is not working for me. I need some attributes inserted into the Http session. A Portlet running in Liferay should do this. When i try to cast the external context into ServletExternalContext i become a Cast exception. Does anybody has any Idea how to do this? Please Help!

Well gee. Maybe it is because you are in a well hmm portlet environment and you should cast it to a well lets get crazy here a PortletExternalContext?

Hello folks. The issue was, that there is a tag in liferay-portlet.xml that looks like this <portlet-private-session>. If set to true you won't be able to communicate with the HTTP-Session. If set to false, all Attributes become shared for the Portlet and HTTP Session. This is specifically for the Liferay Portlal. Hope it helps.
