JSR-168 is a portlet standard that allows any compliant portal to make use of these mini-applications. The potential for providing a mix of applications produced external to an organization, yet consumed internally is great.

There are many companies providing such services in a-la-carte ASP fashion, I thought it would be good to start collecting resources for free portlets. As uPortal is JSR-168 compliant it is likely that we will be consuming such portlets in the future for our University Portal.

Announcement Excerpt from List:

uPortal 2.5.0 general audience release is now available.

http://www.uportal.org/

http://jasigch.princeton.edu:9000/display/UPC/2.5.0

There are many bugfixes and feature enhancements included in this release, perhaps the most notable of which are the availability of DLM as an alternative layout management system and improved JSR-168 portlet support (caching and redirects).

2.5.0 should now be considered the "stable" 2.x version. APU currently has version 2.1.5 deployed. A significant feature changelog can be found here. You can see from this Deployed uPortals list, that many schools are running 2.4.2, or had made plans toward that end.

About a month ago, the uPortal community also released uPortal 3 Milestone 1, representing the next generation of uPortal.
