New Moon on Monday

A month later, is it still all about JavaOne?

A couple of the front page items today reference JavaOne, and that's kind of interesting when you consider that the conference ended a month ago, and that part of the Moscone convention center has now given way to Apple's WWDC, and hosted Google IO before that.

Is JavaOne the "gift that keeps giving", a bountiful source of announcements, opinions, new releases, and innovations that's so immense it takes weeks to work through it? Or is it so big that there's really nothing after it, except for a long silence as wiped out Sun employees and attendees collapse from exhaustion and don't really get going again until Fall?

At any rate, java.sun.com has posted six interviews with Rock Stars of JavaOne 2008. Read on for insights from Joshua Bloch, Tony Printezis, Tor Norbye, Raghavan Srinivas, Chet Haase, and Ben Galbraith.


This week's Spotlight is on one of the most talked-about introductions at JavaOne 2008, the Lightweight UI Toolkit. LWUIT makes it very easy to create compelling UI's that will look and behave the same on all devices using a programming paradigm similar to Swing. It supports platform look-and-feels and themes, touch screen functionality, animation and transitions, rich widgets, 3D integration, painters, and more. The project already has a wealth of information available, including a tutorial, developer's guide (PDF), javadocs, and a wiki. You can also learn more in episode 46 of the Java Mobility Podcast


Also in Java Today, the Accendia Iris Application Server enables high performance Java networking by implementing Remote Procedure Call over a binary wire protocol. The server is handling client request using non-blocking sockets and a pool of execution threads minimizing resource usage when servicing a large number of simultaneously connected clients. The Java 1.6-based project also has a number of demo applications with source as part of its distribution.

The latest NetBeans.tv episode takes a look at TagsME GUI, a NetBeans Rich Client Platform application developed to provide a graphical editor to the JavaME framework, TagsMe. With TagsMe, you define your screens in XML files that are parsed at runtime. You can also download those files, while the application is running, from a web server, allowing creation of online applications. A big component library (buttons, bitmap fonts, animations, sprites, maps...), a plugin architecture, and a script language (very similar to Java) are provided.


Josh Marinacci continues one of his demo series in today's Weblogs. In Java Doodle: fading translucent windows, on PC & Mac, he writes, "this is the next in my series of Java Doodles. This time I'm going to show you how to make a translucent window by setting the opacity value using new apis in JavaSE 6 update 10."

Patrick Keegan discusses JTable Detail Based on JComboBox Selection. "Another question that has come up in the course of my recent postings is how to bind a combo box selection to a JTable's elements (so that the rows of the table are determined by the selected item of the combo box). Here are some rough steps to mocking up this behavior."

Fabrizio Giudici describes a purposeful approach to learning in The JavaFX Circle. "JUG Milano has organized a new initiative called JavaFX Circle: it's about studying and trying JavaFX "live". The thing is basically a series of weekly meetings, starting on next Wednesday. In two hours all the attendees, organized in groups, will work with their own laptop, on a small JavaFX "assignment" defined every day at the beginning of the meeting."


In today's Forums, davjoh wonders about MIDlet states on startup. "I've been reading a bit about MIDlet states and the AMS. According to what I've read, on starting a MIDlet, it is moved into the Paused state, and then into an Active state by the AMS calling startApp(). My question is, why does it do it in this particular order on the first startup? Why does the MIDlet not just execute the startApp() method and move straight into an Active state without having been in a Paused one?"

jimgood asks, What's the proper way to close a window "I know this is just about as rudimentary as it gets, what is the proper way to close a window, such as a custom dialog. It seems like all of the examples in the Swing Tutorial exit on close. My specific need is to capture the values from the input fields on a dialog when the user presses the OK button, then close the window. The only other examples I've seen are setVisible(true). Is that the correct way? To put it another way, assuming the application is done with the window, how should it be closed while the application remains running?"

Finally, loubs001 says it's Easy to Crash the new Plugin on IE. "I've been seeing this problem ever since I started trying the builds of 6u10, and its still happening on b25. sorry I didnt report it earlier... All I have to do is press the right mouse button inside the applet, drag the cursor outside of the applet on to the page, and then release the mouse button. IE shows the normal contex menu, but then goes in to a spin, CPU shoots up to 100% and IE is frozen entirely. Need to kill it with Task Manager. This doesnt happen on FireFox, nor does it occur with JDK6u6 under IE."
