Architecture level Design Pattern

[Rehan Zahoor]

Are there Java 2 EE applications that use design patterns other then MVC on application architecture level?

There is literature about Java 2 EE design patterns but it seems those patterns would only be used in design of modules/ layers. As the Java 2 EE architecture seems very much in agreement with MVC.

[Jeanne Boyarsky]

Yes. Take a look at The Enterprise Application Architecture patterns.

[Rehan Zahoor]

These patterns are not as well known as ,Gang of 4 patterns, are. Would you be kind and answer in terms of Gang of four patterns.

[Rehan Zahoor]

After searching a little on the internet , http://www.corej2eepatterns.com/, is found. It is recommended by oracle too. But it has distributed patterns into Presentation tier patterns, Business tier patterns and Integration tier patterns. Which rather shows that these patterns are used at layers design rather than at application architecture.

[Tim Cooke]

I would not be so quick to dismiss Jeanne's suggestion of the Patterns of Enterprise Application Architecture book. The majority of the patterns described in it are still very much as valid today as they were when published. Martin Fowler's website provides a pretty high level summary of each pattern but the book itself is the complete reference. Highly recommended.

[Rehan Zahoor]

The MartinFowler patterns FrontController and ApplicationController which he has placed in web presentation patterns are in presentation tier patterns of corej2eepatterns. I think other patterns can be placed in some tiers too. But they are all layers design level not of application architecture level.

That went with an older version of J2EE. (I think J2EE 1.4). A lot is obsolete now that we have dependency injection and the like.

That Gang of Four patterns aren't meant to be architectural level patterns. It wouldn't make sense to answer in terms of them.
