Liferay, Vaadin, Glassfish, NetBeans -> best experiences/combination

Hello friends of Vaadin,

what about sharing our experiences with the above combination of tools in form of a matrix/table ?

Right now, i am using Vaadin 6.4.2, NetBeans 6.9, Glassfish 2 and Oracle TopLink which works together very good.

I am looking forward to integrate the application as a portlet into Liferay Portal running on Glassfish, but don’t know about the best versions of each tool to be most effectiv.

Thanks a lot for your help
