GateIn 3.0 is the merge of two mature Java projects; JBoss Portal and eXo Portal. This new community project takes the best of both offerings and incorporates them into a single j2ee deployment archive. The aim is to provide an intuitive user\-friendly portal and a framework to address the needs of today's Web 2.0 applications.
