Not too many questions in Servlet 3.0 for OCPEJWCD 6 exam that I took. If you master HFSJ, you should have great chance to pass. That being said, you still need to be familiar with Servlet 3.0 spec.

Servlet 3.0 is NOT the issue, Charles Lyon do teach servlet 3.0.
What worries me is, that he teaches JSP 2.0 (jsr 152) while I was expecting JSP 2.2 (jsr 245) !!

There are people, who took the exam and passed, did not go through JSP spec, me being one of them. You can read the stories of those who passed in this site. Mock exams should have enough examples to get you familiar with it. I'd suggest that you go through JSP spec 2.2 yourself if you have time and want to be extra careful. Good luck.
