I'm starting to do more work with RAD 6. As with any new release of an IDE, new features have been added and existing ones have been improved (and changed around), so I'm running into some surprises. As I learn how to do little tricks in RAD 6, I'll try to document them here.
RAD 6, officially Rational Application Developer for WebSphere Software, is the successor to WebSphere Studio Application Developer. RAD 6.0 is basically WSAD 6.0. Whereas WSAD 5 is for developing apps for WAS 5 (and WAS 4), RAD 6 is for developing apps for WAS 6 (and WAS 5, and I think WAS 4). Whereas WSAD 5 is built on Eclipse 2, RAD 6 is built on Eclipse 3.
If you don't already have it, you can download a trial copy of RAD 6 to try it out. DeveloperWorks also has a zone to learn more about RAD 6.
What is RAD 6.0?
