Is it just me, or are SUn's EJB Design Patterns simply GoF Design Patterns (and maybe some others), simply applied in the context of EJBs.
Is there any concept of a "pattern" vs "applied pattern?"

Hi Mark,
I think Sun's initiative to come up with patterns specifically for EJB fits into the Applied Patterns perspective.
These patterns are based on the fundamental patterns, which addresses the tier-based problems encountered by an Enterprise Developer.
To my knowledge, the idea of coming out with patterns on a tier basis is something new.It looks so nice to see them classified as Presentation Tier Patterns, Business Tier Patterns and Integration Tier Patterns, instead of Behaviour Patterns, Creational Patterns and Structural Patterns.
Going through the patterns in the above tier category, I realised, they are just extensions of basic patterns like Facade,Indirection,Controller,etc.Hence, we may consider them as Applied Patterns, rather than a new problem-solution pair - a Pattern that has been discovered.
Hope this helps,
Sandeep
