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."

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

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 href="">
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 href="">
Preview of next Draft of JAX-RPC/JAXB 2.0 in today's href=""> 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 href="">
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 href=""> Wandering

The href="">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 href="">
Forums. "Arun has posted a Technology Preview for the EA of JAX-RPC 2.0 and JAXB 2.0 (

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."
