Building Cocoa-Java Apps with Eclipse Eclipse is a gloriously powerful, open source IDE, which is a joy to use when working with Java. It makes sense, then, when writing Java-based Cocoa apps, to use Eclipse. But how? What does Eclipse know about the esoteric world of Cocoa-Java? Well, with a little help from Ant, the flexible build system, you can tell it everything it needs to know. Mike Butler shows you how. [MacDevCenter.com]
The REST of the Web REST, Representational State Transfer, is a collection of design principles that use simple, stateless HTTP for data transfer, without the method-call-like abstractions of RMI or SOAP. Jason R. Briggs shows how you can use this simple architecture, with Jython and Velocity, to develop nimble, loosely coupled web applications. [ONJava.com]

XML Namespaces Don't Need URIs Mike Day argues that using URIs to identify XML namespaces was a terrible mistake that's caused far more trouble than it's worth. [XML.com]
Five Favorite Features from 5.0 A lot has been written about Java 5.0's great new features, leaving David Flanagan to focus on this review of five of his favorite new API features: the Callable and Future interfaces, new APIs for varargs and autoboxing, new ability interfaces, the @Override annotation, and MatchResult. Read to the end, where David reveals a bonus sixth feature, a new language syntax supported by Java 5.0 but known to very few. David is the author of Java in a Nutshell, 5th Edition. [ONJava.com]
Enterprise Streaming The Java Message Service is a lynchpin of J2EE, but is in some ways more difficult and less flexible than more basic forms of communication, like the stream model of the java.io package. However, as Amir Shevat writes, the two are not mutually exclusive--you can write to JMS topics and queues with streams. [ONJava.com]
Simplifying Java with Jakarta Commons Lang Harshad Oak provides an overview of the Jakarta Commons Lang project and shows how the components in this project can simplify and accelerate development. [dev2dev]
Managing Component Dependencies Using ClassLoaders Use of the Class-Path entry within a JAR file's manifest can help you manage external dependencies--to a point. Once you start using multiple JARs that need incompatible versions of external JARs, problems quickly ensue. As Don Schwarz shows, you can get out of this problem by using your own class loader to manage the dependencies. [ONJava.com]
Regular Expressions in J2SE Java applications that perform text searching and manipulation using String and StringTokenizer classes often result in complex code, leading to a maintenance nightmare. Another alternative is regular expressions. Hetal Shah explains how to implement regular expressions using the java.util.regex package, and how it can make your code easier to write and maintain. [ONJava.com]
Form Your Own Design Pattern Study Group Like most complex subjects, design patterns are best learned over a period of time, not in a few sittings. Eric Freeman and Elisabeth Freeman, coauthors of Head First Design Patterns, suggest one way to ease the learning curve (and have some fun along the way): form a study group, using their book. If you're ready to get your engineering team together, the Freemans get you started in this article with a plan to follow and chapter-by-chapter questions to help generate discussion. [ONJava.com]
Quick Start Guide to Enterprise AOP with Aspectwerkz 2.0 Aspect-oriented programming is a great extension to Java, though not yet popular within the enterprise environment.

Eclipse Plugins Exposed, Part 2: Simple GUI Elements Eclipse is largely composed of plugins, but you can't just write any arbitrary code and have Eclipse magically incorporate it. In part two of his series on Eclipse, Emmanuel Proulx introduces Eclipse's "extension points" by showing how to create toolbar buttons, menu items, and dialogs. [ONJava.com]
WS-Security in the Enterprise, Part 2: The Framework Denis Pilupchuk continues his series on developing a WS-Security toolkit by developing a general framework to match the needs identified in part one and by starting to map WSSE features to Java objects. [ONJava.com]
Features: Getting Started with XQuery Bob DuCharme, our intrepid XSLT explorer, turns his attentions to XQuery, the new programming language for XML. [XML.com]
Flexible Event Delivery with Executors Event-handling is critical to any GUI application, and many developers know the hazards of making a method call to unknown or poorly behaved code from the event-dispatch thread. J2SE 5.0's concurrency utilities offer more fine-grained control over how code executes. Andrew Thompson applies that to offer better ways to handle events. [ONJava.com]
Java Component Development: A Conceptual Framework In general terms, a component is one or more classes with an external API that satisfy some requirement. But how do you build components that are really practical--that handle configuration changes or third-party integration well? Palash Ghosh has some ideas about the concepts behind components. [ONJava.com]
Inside WSRP The WSRP protocol allows portals to consume remote portlets running on other portal servers. Learn how the WSRP protocol operates, and how to write portable portlets that can run locally or remotely. [dev2dev]
Building Modular Applications with Seppia Isn't object-oriented programming supposed to be about code reuse? The Seppia framework encourages reuse by allowing you to combine functionality collected in multiple .jar files, stitching the behavior together with JavaScript. Lorenzo Puccetti has an introduction to this interesting framework. [ONJava.com]
SwarmStream: A Next-Generation HTTP Stack for Java Ry4an Brase and Chad Tippin provide an overview of SwarmStream Public Edition's feature set. SwarmStream, a free tool for improving the performance of Java's built-in HTTP networking routines, is among the cool new technologies you'll learn about at this week's Emerging Technology Conference. If you couldn't be there in person, check out our conference coverage page for all the goings-on. [ONJava.com]
Reducing Upgrade Risk with Aspect Oriented Programming Upgrading code in the field is usually frowned upon, if not prohibited outright, because of the risk and expense of pushing code changes through a release cycle. But could you just insert the tiny bit of code you need with AOP? Stephen B. Morris looks at how careful design and separation of responsibilities can make this less risky. [ONJava.com]
A Look at Commons Chain, Part 2 In part one of this two-part series, Bill Siggelkow showed Java programmers how certain design patterns help Commons Chain to define and execute sequential sets of steps.

Aspect-Oriented Annotations Aspect-Oriented Programming (AOP) and attributes are two leading-edge programming concepts, each with typical applications. By combining them, using attributes to indicate where AOP code should execute, you can effectively declare new Java syntax. Bill Burke introduces this new technique. [ONJava.com]
Introduction to WS-Addressing The proposed WS-Addressing specification defines a standard for incorporating message addressing information into SOAP Web services, instead of leaving this to the transport layer. Beth Linker provides an introduction to this specification and its potential use. [dev2dev]
Introducing JBoss Remoting With JBoss World 2005 a week away, JBoss has introduced a new remoting framework. Before you say "another one?" John Mazzitelli hopes you'll take a look at JBoss Remoting, which rids you of RMI-style skeletons and stubs, and offers flexibility and extensibility on both the client and server sides. [ONJava.com]
On-Demand Stateful EJBs EJB session beans can be stateful or stateless, but they can't easily change from one to the other. That can be a problem in certain business situations. Swaminathan Radhakrishnan has a pattern that he says can address this problem. [ONJava.com]
