This week's book giveaway is in the Agile and Other Processes forum. We're giving away four copies of The Little Book of Impediments (e-book only) and have Tom Perry on-line! See this thread for details.
While preparing for EE5 BCD exam, I'm going through MZ notes (thanks MZ!!). The home and component interfaces are mentioned in the notes (for eg while discussing ejb references).
Do I need to have an understanding of how the earlier versions (ejb 2.X) used to work, for the exam?
