I looked at the facts page on portals, but I have some questions.
I am looking for a Content Management\Portal system that is JEE based. JBoss Portal looked appealing, but it seems to have been replaced. So I don't know how stable that project is.
Some features I need are:
-Easy to install and configure
-Is well recognized as a reliable, stable system in the industry and has a decent sized install base.
-Is not expensive.
