All the topics can and do crop up in the exam!
If you need to cram, and time is short, invest in a mock exam simulator (I used Ethnuware and it was IMHO reasonably close to the real thing), do a few tests, and focus on your weak areas.
Make sure you read Peabody's notes on Design
Patterns. Apart from that it's straight
JSP with javabeans,
servlets, EL, and a smattering of custom tags and filters!
Good luck
