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.
For preparation I used Head First Servlets and JSP (excellent book!), specification for Servlets and JSPs from Oracle, javadocs, JavaRanch's links to free mock exams and Enthuware Test Studio (very usefull).
