AOP banishes the tight-coupling blues
Many Java developers have embraced the non-intrusive style and flexibility of aspect-oriented programming (AOP), particularly when it comes to building highly decoupled and extensible enterprise systems. In this article, you'll see for yourself how one of AOP's functional design concepts -- static crosscutting -- can turn what might be a tangled mass of tightly coupled code into a powerful, extensible enterprise application.

Use AOP to maintain legacy Java applications
If you've ever inherited and then had to maintain a Java-based legacy application, then this article is for you. Author Abhijit Belapurkar shows you how to use aspect-oriented programming (AOP) to gain an unprecedented view into the inner workings of even the most opaque of legacy applications.

Improve modularity with aspect-oriented programming
Aspect-oriented programming (AOP) is a new programming technique that allows programmers to modularize crosscutting concerns (behavior that cuts across the typical divisions of responsibility, such as logging). AOP introduces aspects, which encapsulate behaviors that affect multiple classes into reusable modules. With the recent release of AspectJ by Xerox PARC, Java developers can now take advantage of the modularization AOP can provide. This article introduces AspectJ and illustrates the design benefits that result from its use.

Test flexibly with AspectJ and mock objects
Programmers who have incorporated unit testing into their development process know the advantages it brings: cleaner code, courage to refactor, and higher velocity. But even the most die-hard unit testers can falter when faced with testing a class that relies on system state for its behavior. Nicholas Lesiecki, a respected Java programmer and leader in the XP community, introduces the problems surrounding test-case isolation and shows us how to use mock objects and AspectJ to develop precise and robust unit tests.
