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.
Our book covers Tomcat configuration, performance tuning, system security, and deployment architecture. This book doesn�t cover web application development using Tomcat- there are a lot of other good books that fulfill this need. We do cover Tomcat internals too, but not to the level of explaining how to write a JSP/servlet container from scratch.
