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.
There is no such thing as a "best" book. Have a look on JavaRanch There aren't many basic books in there, but there is a review of one by Paul DuBois. See if you can find other things he has written; I have a DuBois at home and liked it.
