I would like to thank you all for providing me advice. I passed it with 91% today.
I highly recommend Ethuware and EPractice Labs. They are very helpful.
Also, I recommend future candidates to search for as many mock exams as possible.
It is all about practice.
I got a lot of questions on EL, deployment, HTTP methods.
I only got one question on each of these topics :AsyncListener, web fragment and servlet security annotations.
I got no question on classical/simple tags and no question on Java EE design patterns.
