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.

This book introduces and provides detailed information about most features and capabilities of GateIn 3.0 such as user/group management and access permissions, using portlets and changing basic interface objects such as skins, language and page orientation.

Refer to GateIn 3.0 Reference Guide for detailed information on all aspects of the project.
