This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
does anyone understand how to read the figures in the book? For example figure 1-4 on page 37 "Effects of protected access". What is the meaning of the letters 'D', 'R', 'I' ? I have not found some explaining text in the preface unfortunately.
