Aspects: An Easy Tool for Annotation Handling?
While many think of Aspects for cross-cutting concerns such as transaction management, persistence and role based security, another key value for them has been as an enabler for Annotations for ordinary projects. Using Aspects as a way to implement annotation handlers is a different way to think of them than as the traditional architect's "cross cutting concerns" view.

Article: Take care of your domain model
Today, many projects focus on Domain-Driven Design, but it is not always easy. One of the most important things are to separate the domain code from the code that only exists for technical reasons. Mats Helander has written an article where he explains how to manage domain models and teaches design patterns and aspect-oriented programming in the process.

Rod Johnson: Are we there yet?
We've come a long way from the first versions of J2EE. We've learned to avoid invasive programming models, we've developed a rich set of frameworks and APIs, we know how to develop applications based around simple objects. Are we there yet? Most of us would answer no to that question. If we're not there yet, then where are we headed next? Spring founder Rod Johnson explores this issue.
