Its been about a month since we released version 2.2 of JBoss Portal, cleverly named "Blade" (ok, so we name our releases after superheros and can't take all the credit). ;-)
To illustrate some of the most important features in the latest release, we have written an article that walks through them. Changes including a JCR-enabled CMS, the concept of Dynamicity (or dynamic portal objects), ease-of-install, and a new consolidated deployment descriptor for rapid development and deployment are all outlined in this article.
As is always the case, the Portal Team is committed to providing an open source enterprise-class portal framework for the masses. Feel free to visit the Portal HomePage or Download Page to begin your journey with the best portal framework open source has to offer.
