Hi all,
Is there any naming conventions for packages and classes which uses a design pattern ?. If yes what are the conventions used for business delegate,session facade, service locator,DAO and any other patterns.

Hi,
that is a good question and one we have considered also. We dont yet cover the naming conventions for classes based on patterns but maybe will in the future. Currently, in the blueprints apps we tend to do some things like naminga class
-AccountDAO etc for DAOs
-For servicelocator we have a class called ServiceLocator viewable at https://adventurebuilder.dev.java.net/source/browse/adventurebuilder/ws/components/servicelocator/src/java/com/sun/j2ee/blueprints/servicelocator/web/ServiceLocator.java?rev=1.4&content-type=text/vnd.viewcvs-markup
-for session facade, its a bit trickier since the name is so long and we cant add "SessionFacade" to the end of each facade class. I think in general we put "Facade" in the name, usually near the end
-For Business Delegat, again it seems too long to add to each class name. So in the past we have added
a "BD" to the names of the delegates. Some examples are at http://java.sun.com/blueprints/patterns/BusinessDelegate.html
-For transfer objects we usually add a TO to the end of the name. Some examples at http://java.sun.com/blueprints/patterns/TransferObject.html
Seems like something we could get a bit more consistent about.
hope that helps,
Sean
