AspectJ is an aspect-oriented programming (AOP) extension to Java that can be used to modularize crosscutting concerns such as error-handling and security policies. AspectJ controls code-tangling and makes the underlying concerns more apparent, making programs easier to develop and maintain. Using only OOP techniques, code for these concerns is scattered and tangled throughout entire programs. While modern Java IDEs provide features for working with encapsulation and inheritance, the AspectJ tools make it easy to work with this crosscutting modularity.

The updated AspectJ development tools suite and Eclipse AJDT plug-in will be used to demonstrate new tool features including incremental building, bytecode weaving, crosscutting structure views, code assist, and debugger support. Some common crosscutting concerns of an existing object-oriented system will be mined and refactored into a modular aspect-oriented implementation. The tools will be demonstrated on an enterprise system, and new features for working with crosscutting in large systems will be shown. The integration of AspectJ into existing development processes will also be reviewed along with JBuilder, NetBeans, Emacs, and command-line tool support. Installation of the tools and project setup will demonstrate how easily AspectJ can be applied to existing Java systems. In addition, a preview of the next-generation AJDT plugin will show how advanced IDE features such as refactoring support will work in upcoming releases of AJDT.
