T7: Enterprise Aspect-Oriented Programming with AspectJ

Attendees should have experience doing object-oriented design and enterprise
Java development, and should have some previous exposure to aspect-oriented
programming (at least a tutorial). Previous experience with AspectJ is
beneficial but not required.
Aspect-oriented programming (AOP) has become a hot topic for enterprise
development, with recent news of support by IBM, JBoss, BEA, Oracle, Eclipse,
and IntelliJ. Behind the news headlines, however, are critical questions:
- How real is AOP for the enterprise?
- What problems can it solve today?
- How does it apply to enterprise applications?
- How can one make an informed decision about trying to use AOP?
- What is the best adoption strategy?
- What are the long term possibilities for AOP in the enterprise?
This tutorial will tackle these questions and give developers, architects, and
technical managers an introduction to AOP for enterprise Java application
development. We will provide both a conceptual road map and tangible examples
of how AOP works and where it can be beneficial, as well as discussing
anti-patterns (i.e., how not to use AOP). Over the course of the tutorial, we
will demonstrate the use of AOP for security, error handling, policy
enforcement, testing with JUnit, systems management with JMX, and more. The
examples will be implemented in the AspectJ programming language (a popular and
seamless aspect-oriented extension to Java) and will incorporate major J2EE
technologies such as servlets, JSPs, and EJBs.
At the end of the tutorial, participants will have an understanding of both the
potential and the pitfalls for applying AOP in a J2EE context. The tools used
in the tutorial are all freely available as open source software, so
participants will be able to use the techniques shown in their own projects.
