Amazon Kindle SDK (KDK) uses CDC Personal Basis Profile
By Karol Harezlak on Feb 06, 2010
So it's true. Amazons KDK is Java ME CDC based with Personal Basis Profile. Java ME PB Profile provides a complete Java ME application environment for example it contains java.awt or java.rmi. Interesting that on KDK FAQ page I found information about support for all major Java IDE including Netbeans.
