Terrence Barr highlights the Java Card 3.0 Connected Edition in this week's java.net Spotlight :
Java Card 3.0 was released a couple of months ago - and the second update (version 3.0.2) is scheduled for December. If you haven't paid much attention to Java on smart cards because you thought it's not "real" Java - well, look again.
Terrence points out that the limitations in Java Card 2 are in part related to the fact that Java Card 2.0 came out about 10 years ago. If you think of how much has changed in mobile technology in the past ten years, it feels like 10 years ago was the age of the dinosaurs.
And so, it makes sense that there is a lot of change between Java Card 2 and Java Card 3.0. Actually, the Java Card version numbering / edition naming is a bit confusing at this point. For Java Card 3.0, there is a "Classic Edition" and a "Connected Edition." Even when I first saw this several months ago, when Java Card 3.0 was announced, I considered it confusing. Java Card 3.0 "Classic Edition" is really a maintenance release of Java Card 2. So, why are they calling it Version 3.0 instead of calling it Version 2.something (since it's backward compatible with Version 2.2.2)? Sounds like the marketing department's idea, no?
Anyway, it's the Java Card 3.0 Connected Edition that includes all the big enhancements. Terrence calls this edition:
the dramatically enhanced next generation of Java Card technology. The Connected Edition contains a new architecture that enables developers to integrate smart cards within IP networks and web services architectures. It supports extended Java Card applets and servlets to allow for these new capabilities in addition to also supporting classic Java Card applets.
Highlights of the Connected Edition:
- JDK 6 compatible VM
- Full Java language support
- Rich APIs
- Three application models and two library models
- Servlet Container with Servlet 2.5 support
- Size still measured in KBytes
- Netbeans plug-in for easy development
See Terrence's post and the Java Card site for the details. There's also a new Java Card project on Kenai.
In Java Today , Java Champion Jim Weaver posted The JavaFX How2 Compendium :
I'd like to make sure that you know about a great new JavaFX resource that Maya Venkatraman, Scott Hommel and others have been working on. This resource, located on the JavaFX.com site, is called the JavaFX How-To's (although I like to call it the JavaFX How2 Compendium because it is a concise, yet comprehensive compilation of how to get things done in JavaFX)...

Josh Marinacci pointed out that Neil Bartlett will be presenting "JavaFX in Eclipse" at Eclipse DemoCamps November 2009/London :
Since April, Neil has been working for Sun Microsystems to advance their tooling for JavaFX within Eclipse . In this demo he will show the current progress and preview some up-coming features. He will also show a demo of using OSGi for runtime modularity in a JavaFX application (based on original work by Johan Vos ).

Aaron Houston posted DEVOXX Day 3 - JUG BOF with James Gosling - MP3 recording :
Here is a raw recording of the JUG BOF at DEVOXX with James Gosling who was our special host. We had 56 Java User Groups represented at DEVOXX; We had 60 people in the room with James. Detailed list of topics discussed by timing marks in the MP3 recording. MP3 is 19MB to download and is 40+ min long. Here's bits and pieces, so here is the disclaimer: Please Listen to the MP3 before making any judgments/opinions on the accuracy of the transcript...
Cay Horstmann comments on the "tantalizing announcement" at DEVOXX in Closures? In Java 7??? :
Today, a tantalizing announcement by Mark Reinhold about closures in Java 7 has made its way through the twittersphere. On the same day, Neal Gafter updated his closure proposal (known as the BGGA proposal, named after the initials of Bracha, Gafter, Gosling, and von der Ahé, and not at all related to the B. G. G. A. organization )...

In our current Spotlight , Terrence Barr invites us to Check out Java Card 3.0 Connected Edition: Real Java, just really flat ;-) : "Java Card 3.0 was released a couple of months ago – and the second update (version 3.0.2) is scheduled for December. If you haven’t paid much attention to Java on smart cards because you thought it’s not “real” Java – well, look again. It’s true that Java Card 2 was very limited in many ways – a testament to the kind of technology you had available on smart cards 10 years ago. There are billions of these out there today..."
