The guys at Liferay have unleashed Liferay 5.2 upon the world.
Liferay is a fantastic Java based portal system. I’m currently involved in a project to deliver a website integrating a CMS system and the Liferay portal. Through development of JSR 168 based portlets written using the Spring Portlet MVC framework, Liferay can enable a huge amount of flexibility to the business to create, update and maintain a hugely complex site with little effort.
As an open source product, it is a shining star of what can be achieved with a focused team. Liferay has become an enterprise level product powering the web sites and intranets of several large brand name companies.
All in all, congratulations are in order for a VERY good job done!
