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.
Head First Servlets and JSP is the most recommended book, but if you've already got 1.3, maybe you could just refer to some ranchers' notes and browse through the spec. See the Links page (Rancher Notes)
