Does the Core J2EE Patterns from SUN still hold for the new Java EE 5 architecture. I started to read this book, was wondering if it would make sense for the new version of SCEA.
Thank you
Rama Z.

Hallo Rama

Hope it helps

Yes, J2EE patterns are part of the new exam and they weren't examined in the old SCEA. Just GoF patterns...

If you want a brief but useful overview of the J2EE patterns take a look at this:

Actually, there was an interesting thread in this forum on that very topic - which J2EE design patterns no longer apply with JEE5. Some thought DAO was dead with POJO based JPA, and others thought resource injections with annotations made the ServiceLocator pattern obsolete. Personally, I'm not so sure, but I can certainly see from where those thoughts would come.

Hmmm, also with the advent of Spring framework and component based Web frameworks, some of the patterns are not widely used or not required.

Thank you for all the replies. A follow up question - are we suppose to know detailed strategies and implementation of patterns. eg. Application controller Strategies - command handler, view handler, Transform Handler and Message Handling.
Or is it good enough for SCEA if we know the gist of each pattern?
