In the Featured article called Asserting Control over the GUI: Commands, Defaults, and Resource Bundles, Hans Muller has shown "that a simple combination of the current J2SE classes are sufficient to bind Swing GUI components to actions in a declarative form that's easily localized."

Muller takes another look at the Swing event model and "demonstrates how one can separate an Action's visual properties into a ResourceBundle that's loaded through Swing's UIDefaults API. In addition to enabling localization, this approach shifts some of the GUI from code to a declarative representation. That's an advantage for large applications, because the declarative aspect of the application can be developed independently from the code."

Note: (1) The projects side of java.net will be down for 15 minutes today around 10 am PST. (2) The projects side of java.net will be down for up to 18 hours on February 2, 2005 for a tools update.

In Also in Java Today , in the JavaWorld article Event-driven services in SOA , Jeff Hanson describes "designing an effective event-driven and service-oriented platform using Mule, a lightweight event-messaging framework designed around an enterprise service bus (ESB) pattern. Components and applications can use Mule to communicate through a common messaging framework implemented transparently using Java Message Service (JMS) or another messaging technology."

Sometimes your javadocs are revealing a bit too much about your application. As John Zukowski writes about this in a recent Core Java Tech tip Hiding ListResourceBundles from javadoc. He explains, "The classes for the list resource bundles must be defined in public classes. The problem is that when you run the javadoc tool on your source tree, the API documentation for the resource bundle class will appear with the other classes if located within the same package. This level of implementation detail should be hidden. That's because if you later change to a PropertyResourceBundle, the public class will be gone, changing the public API for your product." This tip explains how to hide these details from javadocs.

Eduardo has posted a link to a Preview of next Draft of JAX-RPC/JAXB 2.0 in today's Weblogs . Echoing a forum post he writes " Arun has posted a Technology Preview for the next draft of JAX-RPC 2.0 and JAXB 2.0 to encourage the developer community to provide feedback on these two very important specifications."

Ryan O'Connell blogs on Implementing the State Design Pattern using Enums. " The Enum construct is a new feature added to J2SE 5.0. The Enum construct allows developers to create type safe enumerations. The enum feature also seems like an ideal way to implement the State design pattern."

James Gosling reports in from his travels to Australia in Wandering OZ. "I'm in Australia this week giving some talks and visiting folks. Yesterday I was in Newcastle speaking at the Australian Computer Society, which was a wonderful experience. A great group of people."

In Projects and Communities, the GELC's Daniel Brookshier welcomes new projects including JeLSIM, a toolkit for producing educational simulations, and Recuitment, a set of tools for recruiting.

The JavaDesktop community is featuring Ken Russell's JCanyon demo, which has been revised to work with JOGL. JCanyon is a simple, web-started flight simulator -- implemented completely in Java.

There is a new discussion on the Technology Preview of JAX-RPC 2.0 and JAXB 2.0 EAs launched in today's Forums. "Arun has posted a Technology Preview for the EA of JAX-RPC 2.0 and JAXB 2.0 (http://jwsdp.dev.java.net/servlets/NewsItemView?newsItemID=1849). The TP includes a rewrite of the WS-I Sample Supply Chain Management Application using the latest (Early Access) version of the JAXB 2.0 and JAX-RPC 2.0 specs."

Walter Bruce continues the discussion of Lightweight Objects, Tuples, "I think you are missing the point of extended primitives. They are not objects and have somewhat different semantics (eg pass-by-reference vs pass-by-value). What they gain is efficiency, not base functionality."
