OpenNMS: enterprise-grade network monitoring platform
OpenNMS [1] is an enterprise-grade network monitoring platform developed under the open source software model. It consists of a community-supported, open-source project as well as an organization offering commercial services, training and support.
The full featured monitoring solution is written in Java and is released under GNU Public License. I used to use Nagios, but OpenNMS seems to be a Nagios killer. At least it is worth taking a deep breath. Get an impression on your own and try out the demo (username:demo password:demo).
In the current stable release technology preview series 1.7.0, OpenNMS uses the Spring Framework (WP: Spring Framework) 2.5 and a RESTful Interface was added.
qooxdoo: Open Source RIA Framework
qooxdoo [1] is a comprehensive and innovative Ajax application framework. Leveraging object-oriented JavaScript allows developers to build impressive cross-browser applications. No HTML, CSS nor DOM knowledge is needed.
It includes a platform-independent development tool chain, a state-of-the-art GUI toolkit and an advanced client-server communication layer. It is open source under an LGPL/EPL dual license.

Ext JS: JavaScript library for building RIA
Ext [1] is a JavaScript library for building rich internet applications (RIA [2]) using techniques such as AJAX, DHTML and DOM scripting.
Originally built as an add-on library extension of YUI [3], Ext includes interoperability with jQuery and Prototype. As of version 1.1, Ext retains no dependencies on external libraries, instead making their use optional.
Ext JS ist released under GPLv3 (since version 2.1, was LGPL before). Generally LGPL makes much more sense for libraries as GPL does, but anyway… they now have a commerial license too.
Check out the examples.
