In this developerWorks article, Ron Bodkin presents practical guidelines for incorporating aspects more deeply into your development practice. He describes various stages of AOP adoption, offers examples of learning applications and guidelines for success at each stage, and provides a survey of the AOP techniques and applications.

Apple's Zero Configuration Networking ("Rendezvous" or "Bonjour") facilitates spontaneous discovery and communication not only between devices, but also between software services running on different network nodes on a LAN. A recent article looks at how to register and discover services with ZeroConf's Java APIs.

The NetBeans project has released Jackpot, a module that helps you reengineer Java source code by safely making sweeping changes to potentially large bodies of code. It includes a rules language in which you can specify transformations.

A popular way to scale up a Java application is to distribute its processing on a cluster of independent servers. Such distribution requires software tools that help split an application's work into smaller pieces and coordinate work between cluster nodes. The open-source Java Parallel Processing Framework aims to provide such tools.

There has been a lot of discussion around the net, including at Artima, about Gosling's recent comments concerning PHP, Ruby, and other languages. But until now, the full transcript and context wasn't available.

While the stateless model of client-server interaction allows a servlet to service requests from any client, it also puts the burden of state management on the developer. Continuations, a feature of Ruby and other languages, can help ease state management chores. In a recent article Bruce Tate shows how to use this technique in Java.

Grizzly is an NIO-based HTTP front-end of the GlassFish J2EE server project. Project lead Jean-Francois Arcand compares this NIO-based HTTP server with the most recent Tomcat HTTP implementations, showing that using non-blocking sockets allow a server to scale up.

In J2EE 5, a significant amount of glue code is required to use JSF and EJB 3.0 together, and that glue code often has to deal with difficult application issues. The JBoss Seam projects aims to simplify that interaction by bringing EJBs closer to the Web tier.

RIFE is a "full-stack component framework to quickly and consistently develop and maintain Java web applications." In this article, Geert Bevin provides an introduction to RIFE with an example blog application.

Although memory leak possibilities in Java programs have been discussed and documented in recent years, a new article summarizes potential memory leak dangers in J2EE apps. The article provides a useful summary, although not everyone may agree with all its conclusions.

Swing has seen a burst of activity and development in recent years. SwingLabs is a Java community project that aims to create a layer of widgets and components above those already in the J2SE API. The latest SwingLabs tool is a Wizard API that lets you build setup and configuration wizards for a Swing application.

In a recent IDN interview, Jason Hunter makes a few bold claims about XQuery, the XML query language. While many efforts at query languages have emerged in recent years, few achieved the ubiquity of SQL and free-text search. Will XQuery fare better?

Recent years have seen the proliferation of Web frameworks that aim to simplify the development of complex Web applications. One such framework, Wicket, promises to rely less on external configuration files and more on Java code to speed up Web application development. A recent article introduces Wicket and compares it to other Java Web frameworks.

JSP and JSF each has its own expression language, and the two are sufficiently dissimilar to make integration between these technologies hard. A unified expression language, recently added to the JSP Standard Tag Library, aims to make using JSP and JSF together easier.

JSP and JSF each has its own expression language. Those languages are sufficiently different to make working with these technologies together hard. A unified expression language recently added to the JSP Standard Tag Library aims to make it easier to use JSP and JSF together.
