问题 I started developing a portlet based application using WebSphere Portal and now I am switching my development environment to Liferay.

问题 I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible.
