This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I found the "Struts Survival Guide" to be very useful (as a struts newb myself). There is a free PDF version of it online, you can probably just search for it. I found it was more helpful than the Struts for Dummies book that I purchased.
