This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori 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.
