Don't forget NetBeans, the Rich Client Platform. Lots of applications are built on it (Light Analysis, Energy Consumption Management, Petroleum Engineering App, Swedish Trading Client & Swedish Defense Research App, Open Source Stock Trading Platform, Jewelry Customer Manager -- these are news only from the last 3-4 months), even NASA uses it. It's crucial for Oracle to sustain NetBeans development and not to favour their JDeveloper IDE (cause the latter isn't a platform).
