Developers who properly use XML with J2EE develop the most powerful enterprise systems that can be built today. J2EE and XML Development is a rich yet concise guide that teaches how, where, and why to use XML in each layer of a J2EE application.

NEW J2EE PATTERNS
Semi-Singleton
By Robert Boothby
On certain occasions it is desirable, but not essential to have a shared, single instance of an object. Semi-singleton applies to situations where the object can be lazily instantiated, invalidated and thread synchronization is to be avoided. It is of particular use in the J2EE environment when it comes to caching InitialContexts and Home Interfaces.
Read more on this pattern.
A Pattern Combining the Business Delegate and Factory Pattern
By Sourav Mazumder
The Business Delegate Pattern decouples the client from the Session Bean facade. However, the client has to hard code the Business Delegate class name. This can lead to messy code in a large project. This pattern basically uses the Business Delegate pattern with a deviation in which the client code can use the factory pattern to get the name of the business delegate class dynamically without hard coding the name.

NEW APP SERVER REVIEWS
JBoss - Invest in People, not in Infrastructure
By Pieter Van Gorp
JBoss offers a powerful and complete operational infrastructure. It lacks both administration tools and tools for the "corporate developer" (à la BPM). I believe it's possible to achieve the same performance as with a commercial product, but it requires a larger investment in training, prototyping and/or consulting.
