Oracle APEX 4.0 early adaptor has been announced. It was just reported by David Peake on his blog. All you need to do is go to http://tryapexnow.com fill in some details and request a workspace. In a few minutes I was looking at APEX 4.0.
As you can see in the text box on top of the screen, it’s hosted on the Amazon cloud.
Now it’s time to give it a try!
