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.
p.s. RH8 already comes with a Java compiler called gcj. However, I haven't had much success with it. It may even come with another Java compiler, but I doubt that it's SDK 1.4 because RH8 has been out for a little while.
