AJAX has forever altered user expectations regarding the experience delivered by the Web. In today's world, users sit at the edge of their seat waiting to see what scrumptious eye candy AJAX will serve them next. Some of the more notable visual effects and desktop-like interactions include Prototype-esque fades, Dojo style fisheyes, the near ubiquitous drag-and-drop, and, of course, who can live without the entertainment provided by the assortment of animated loading icons that now distract us while AJAX does its asynchronous 'thing.' Yes, it would appear that AJAX can do it all and that no desktop visual effect or gesture is safe from being outsourced to the Web.... more »

There have been some big back end changes going on in the SwingBuilder to support some fairly mild but useful features. With exciting things like bind() and animate() they can get lost in the mix. Here are some New and mildly Entertaining features in Groovy's SwingBuilder (note that some of these have shown up after Beta-3, so snapshots are still the best place to go until the despots start rolling relese candidates).... more »

It’s been bugging me for a while that the JDK source is not included on the Mac version of Java and thus I can’t walk into the source in Eclipse. I finally got around to fixing that. If you want the source, you have to join the Apple Developer Connection (free account is fine) and find under the Java downloads the “J2SE 5.0 Release 5 Developer Documentation”. Download this (69 MB) and install the package. This will drop a src.jar, and the javadoc in both HTML and jar form at /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home.... more »

I definitely think that dynamic languages for Java platform is an important topic. In that context, a Scripting API as a standardized scripting framework has its own role for Java developers. It is definitely a good thing it is included in JDK 6, but the lack of proper support for earlier JDK’s, in my opinion, slows down its wider adoption.... more »

Which IDE is best for writing Java code? Leaving aside NetBeans (a big assumption given that it now has excellent Ruby and JRuby integration), the choice was between Intellij or Eclipse. IntelliJ while commercial, wasn’t too expensive and ‘just worked’ out of the box. Eclipse, if you were willing to install multiple plugins, could be more powerful but more intimidating.... more »
