As per your suggestion, changing struts2 version to 2.1.8 fix the problem. Thanks!

Please create a GitHub repo with your code and I'll take a look. Note that the examples from the book were tested only on Tomcat, and a pretty long time ago. I'll need any server details you're using. Also note that S2 is fairly different now than when the book was written.
