Column icon Software engineers are notoriously obsessed, sometimes excessively, with performance. While sometimes performance is the most important requirement in a software project, as it might be when developing protocol routing software for a high-speed switch, most of the time performance needs to be balanced against other requirements, such as functionality, reliability, maintainability, extensibility, time to market, and other business and engineering considerations. In this month's Java theory and practice, columnist Brian Goetz explores why it is so much harder to measure the performance of Java language constructs than it looks."

A Killer App for AOP

JBoss 4's implementation of AOP makes the development, deployment, and maintenance of middleware a snap

Bill Burke and Marc Fleury

Pioneered at Xerox's Palo Alto Research Center (PARC) in the late '80s and early '90s, aspect-oriented programming (AOP) has greatly influenced modern software development, from the latest research at IBM, to the tag-driven development nature of Microsoft's .NET and C# environments. Indeed, AOP has been gaining an even wider audience of late: its research community is extremely active, a number of open source projects offer a wealth of implementations, and, as a natural complement to object-oriented programming (OOP), developers are discovering that AOP provides for more intuitive, extensible, and flexible middleware. If you're an enterprise software developer, JDK 1.5, the newest release of Java, combined with JBoss AOP, available in JBoss 4, may just be the best thing since sliced bread."

by Bill Burke, coauthor of Enterprise JavaBeans, 4th Edition
03/02/2005

Annotations are one of the new language features in J2SE 5.0, and allow you to attach metadata onto any Java construct. Meanwhile, Aspect-Oriented Programming (AOP) is a fairly new technology that makes it easier for you to encapsulate behavior that is usually messier, harder, or impossible to do with regular object-oriented (OO) techniques. Together, they make a new powerful combination that gives framework developers a more expressive way of providing their APIs. This article dives into combining these technologies using the JBoss AOP framework in various coding examples to show how you can use this combination to actually extend the Java language."

Many Web developers enjoy the versatility and ease of use of PHP, but sometimes they need to access existing business logic in a J2EE application server. In this article and through code examples, learn how to use the new SOAP extension in PHP 5 to access a J2EE application using Web services, without having to leave the PHP environment or learn a new programming model."

Using Annotations to add Validity Constraints to JavaBeans Properties


By Anders Holmgren, March 2005

Articles Index

Currently there is no standard way to add validity constraints to Java classes. This is in contrast to other languages like XML in which (using XML Schema) relatively rich constraints may be specified. With the advent of annotations (JSR 175) in the Java 2 Platform, Standard Edition (J2SE) 5.0 a convenient mechanism now exists to allow such constraints to be specified in the Java meta model. This article explores how annotations might be used for this purpose and discusses why this may be an important capability."

Suppose that one day you are driving to work and end up arriving late for an important meeting. You aren't able to present your revolutionary idea, so your clients aren't going to use it. You're frustrated by your tardiness and vow to never make the same mistake again. So how do you diagnose the cause in order to avoid a replay? How about this checklist?"
