Is there a published list of Java EE patterns just like we have for J2EE. I have come across pattern names for Java EE like model facade, entity view, Exportable Service Broker etc. I have not come across DAO but instead EAO for accessing entities. Are these names official?

Most of the old design patterns still apply, although dependency injection and JPA entities can make you question the DAO and Service Locator patterns.

Here's a neat thread discussing which J2EE design patterns no longer matter in JEE5:

Which J2EE Design Patterns are Obsolete in the SCEA5 JEE5 Certification Exam?
