Hello Budi,
First of all thank you for your book. I've already bought it in Amazon (Kindle edition).
I had not been able to found a good book/tutorial for the Servlet 3 specifiaction.
Although I develop using JSF2, you say that one won't be able to code effectively and efficiently without an excellent knowledge of Servlet and JSP.
I think you are right, in the end JSF uses a Servlet as its "point of start".
My question is: For simple/small applications, what do you recommend? To use "plain" Servlet/JSP or a framework (Struts2, JSF2, etc...)?
Thank you !
