As we all know several patterns that are mentioned in "Core J2EE Patterns" are now used by JEE Platform itself i.e. Controllers, View Helpers or Composite Views in JSFs.
The question is, should we describe all patterns that are present in our architecture or only those that were reflected in our design/classes?
I am not listing them as such. I am using stereotypes in the 'class' diagram itself to show that. For ex. '<< DAO >>', '<< Facade >>'. I think the exam is about solving the business problem in an elegant way - patterns help us to get that elegance for sure, but we should not strain ourself to include patterns just for the sake of it.
