Hello everybody!
When I first started to teach myself about Servlet and JSP(because these two are like JavaEE-101), I was looking for a reference book that can give me the logic and make me understand everything clearly. That book is "Head First Servlets and JSP". So I definitely recommend this book if you are new to JavaEE and looking for somewhere to start or you are preparing for an exam. I read this book now and then and tried to experiment all the small task the book gives to readers. One of those tasks was "Beer Suggestion Project" which is very basic yet again very suitable for beginners. Here in this post you can find that project(you can also find it in the book though :)).
My project structure was like below at the end.
