This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Well champ, you have to follow the format proposed by Sun in the interface given to you in the assignment. So the imgs package would stay inside the suncertify package (and just a tip, images are not required in this project).
Anyway, as soon as you are done with it, you can check the structure of your project using Roel's test case + Ant build script, to make sure everything's correct.
