EJB specifications

I've often heard that reading the specs is one of the best ways to prepare for the certification.
I've just downloaded the EJB 2.1 specs and am starting to read it. Now, my question is: Does this 2.1 spec also cover the materials in the 2.0 spec? Is reading the 2.1 spec enough or does it just cover the difference between versions?
What about reading the specs for other technologies (ie, Servlets, JSP, etc)?

Well, until Head First EJB comes out

I vaguely recall a post by Kathy Sierra (I think) suggesting that we stick to the 2.0 specification, since there was nothing from the 2.1 specifications in the exam.
I believe each specification is stand alone - that is each version completely covers the topics and has details of what has changed since earlier versions. So the 2.1 spec should contain everything you need, however you are also going to have to read the "whats changed" sections

Great idea for general knowledge. But not required for this exam.

In case you are preparing for SCBCD, it would be smart to stick to EJB 2.0 specifications. Of course 2.1 would highlight enhancements introduced in 2.1 but you would still be going through lot of redundant material. Please note that SCBCD is the ONLY exam (I know of) that covers just one document (EJB 2.0 specs) cover to cover and no more. No question on patterns, no question on whether and when to use EJB and not even on best practices.
For other exams like SCWCD knowledge of specs would cover most of the requirements of the exam but you still need to read a little about patterns for completeness.
