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.
The one that I picked up is Beginning J2EE 1.4 from James L.Weaver, Kevin Mukhar and Jim Crume. I haven't seen the other books, but so far I like this one because it has screen shots of how to properly set up your environment that was a great help. I know Java, but I don't know Windows Systems, and didn't know that I could define DOS variable names, little alone how to do it.
