Exam Gotchas?

Hey all, studying towards my SCWCD, got the exam in little under a month. I've been using the Head First JSP/Servlets book, V.good! and this forum, also excellent.

I wondered if there are any things to look out for in exam? things that are a similar that the exam will try and catch you out. Like the SCJP5 exam did by asking a question on output when the code doesn't actually compile.

Some of the things I thought they might try and do to catch you out would be:
- trying to write to response after doing a RequestDispatcher.sendError()
- order in which filters are called?
- which servlet is called given similar url patterns?
- using page instead of file in the includes directive.

Anything else I should pay extra attention to?
Maybe things like calling method on GenericServlet when it exists on HttpServlet.

Any thoughts would be most welcome, Thanks,

- Getting confused with Servlet config and Servlet context.
- Using doAfterTag() in simple tag handlers OR using skipPageException in classic tag handlers.

I think all such things would be covered in 'Watch It' boxes in HFSJ.

That is a pretty good list of some of the things they like to test. If you check out my material I have put some of the things that can trip you over in what I call "Key Points". See the sig of this post.
