This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
The .zip for the sourcecode examples on Forum Nokia (i.e. 'MIDP_Example_Applications_1.4.zip' or whatever the latest version is) contain Ant build files and the top-level 'midp/examples' README file has more info. Some of the examples use the Nokia UI API.
