OpenSource Portal Frameworks

Yesterday, I came to know about list of OpenSource Portal Frameworks.

Apache Jetspeed 2
Liferay
JBosss Portal
Gridsphere


All three framework are JSR-168 Compliant.

Apache Jetspeed from Jakarta opensource community.

Liferay got nice Portal UI features.

JBoss Portal is nice.

Gridsphere is part of the Gridlab Project. GridLab was funded by the European Commission under the Fifth Framework Programme of the Information Society Technology, contract number IST-2001-32133. The GridLab Project officially ended in April 2005 and eagerly waiting for Grid Lab 2!

Personally, I would go with Gridsphere!!
