This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I've been having great success recently with Resin from http://www.caucho.com/ . It's free, comes with source code, implements Servlets 2.2 and JSP 1.1 and is very fast. Check it out!
