writes "Liferay Opensource Enterprise Portal 1.8 Released. Liferay (http://www.liferay.com
)was developed out of the lack of a lower end portal solution. The result is a pretty deep solution that handles not just the basic users and portlet drawing, but also has a full administrative interface, documented support for all of the major databases, documented support for the main J2EE application servers (JBoss/Jetty, JBoss/TomCat, Oracle AS, Pramati, WebLogic, Orion, and more coming soon, see www.Liferay.com
for versions and latest details) and single sign-on capabilities and multiple language support.In addition to the included portlets, Apache Lucene is used to enable document searching.
Liferay is a true J2EE application, relying on
numerous patterns, EJBs and built on top of the Struts platform. An XML-based
registry is also used to store portlets. A number of portlets are included,
including a guestbook, a calendar, a mapping utility using Expedia, news, polls,
a document library, live stock information and more . It's a great start for
anyone launching a portal project.
Liferay is clearly a good option, especially
for anyone who is familiar with Struts. Of course because Liferay is a complete
application, it will work well for many companies out of the box.
