On to GlassFish v3 OK, let's review. The plan for GlassFish v3 is to move to an modular and extensible platform, supporting OSGi, with support for dynamic languages and Java EE 6. That's a tall order, so to break things down into more manageable chunks, the team announced earlier this year that they would begin with a Prelude to GlassFixh v3, whose contents would be limited to the big...
Clinging to Java SE 5? Today's feature article takes a somewhat roundabout way to get pixels from OpenGL (specifically JOGL) over to a Swing GUI. Rather than using the provided AWT or Swing components, it renders its pixels to an OpenGL pbuffer, and then copies those pixels into a Graphics2D. The authors' benchmarks show the performance hit isn't bad, and I think it's an interesting thing...
Getting psyched for NIO.2 We covered JSR 203, "More New I/O APIs for the Java Platform (NIO.2)" a few months back, in the form of Elliotte Rusty Harold's extensive preview. What's surprising is reading that there's still more useful stuff coming in NIO.2 beyond the established coolness of file attributes and reliable copy and move methods. Over on Javalobby, Alex Miller looks ahead to JSR...

Controlling stuff (or not) with Java Has the coolness of web programming trumped the appeal of interfacing with physical devices? When a lot of us were young, the most fascinating kind of programming was hooking up sensors or motors to an Apple II's paddle control and writing programs that actually interacted with the real world. This kind of thing seems to be rare in Java. It does exist,...
Will a troubled economy ding us techies? I'm sure a lot of us are paying more and more attention to economic and financial news over the last few months... I just re-subscribed to BusinessWeek after a long time away, feeling that the sudden on-rush of the credit crisis had taken me by surprise, certainly the kind of thing you don't want happening when you're trying to buy a house (and sell...
Getting thread pools right... really right Have you ever noticed that a lot of people who present the idea of pools in the abstract -- whether for database connections, threads, whatever -- seem to implicitly assume that the demand for the pooled resource will never exceed the number of available resources? In other words, the first time someone explains this to you, they show you why it...
Spam and elections, unrelated A few random items to bring to your attention. First, we've had spammers trying to hit different parts of the java.net site: article comments, weblog comments, forums, etc. It's something we've been dealing with for years, and our response is the same: we immediately delete the user and all their posts, then send an e-mail to the address they registered with...
More like two years ahead, now that they've got Java-powered TVs So here's an interesting bit of news about a java.net project delivering the goods. You might remember a few months ago (was it last year?) when the Open Cable Alliance set up the OpenCable project as a home for resources related to the OpenCable Application Platform (OCAP) initiative, marketed under the name "tru2way", whose...
REST versus SOAP, must there only be one? Almost as spirited as the battle over closures is the debate over web service architectures: SOAP versus REST. If anything, it sounds fairly one-sided: the REST side blogs a lot, yet you don't see as much blogging from the SOAP side. Maybe they're too busy developing new web services to engage their critics? I don't have a stake in this fight, so...
