J2EE Patterns

HI,
One of the objectives of the Architects Exam 310-052 is to know the Java 2 EE core design patterns. Now, I believe all these patterns are still core exam objectives and must be known even though some of them would not be used with the latest Java EE technologies. For example, you still need to have good understanding of things like DAO and Domain Store when the sensible thing to do would be to just use JPA.

So my question is what other patterns do you consider obsolete with latest technologies?

And can you confirm that we really need to know all these patterns?

Thanks.

For the exam questions, you certainly need to know all the design patterns. Even though you are a Java EE 5 architect, you need to know how J2EE applications may have been implemented or maintained.

Here's a JavaRanch thread on just that topic of obsolete design patterns:

Which Design Patterns are Obsolete with Java EE 5 and 6?

Yes, you should know them all, but for the first part concentrate on the problem each pattern solves, the actual implementation details are not asked.
