The JVM co-opts Visual Basic A comment from
This was mistakenly proclaimed as a "second language" for the the JVM, something that Ken Arnold noted was off by about 198 languages. But still, it's a reminder that Java-the-language and Java-the-VM are two different things -- meaningfully coupled, but neither dependent on the other -- and that we continue to see profound interest in bringing other languages and their developers to the JVM, as it represents a popular and important solution to issues of compatibility, security, and more. There are several helpful responses to be found in today's Forums.

Re: EJB3 @generatedvalue not working, Chris Campbell talks transparency in Re: [JAVA2D] Transparent pixels in PNG/Buffered Image: "First, it's best to avoid getScaledInstance(); there are better/faster ways to do what you want (see the Java 2D FAQ [1]). Second, in order to preserve the transparency from your original image, you'll need to call g2d.setComposite(AlphaComposite.Src) before copying the original into the new image. Allow me to suggest some code that will resolve both of the above issues in fewer steps." In Also in Java Today, the interview JSF and JSP: What's New in Java EE 5: A Conversation with Ed Burns and Jan Luehe features a talk with Ed Burns (co-specification lead for JSR 252, JavaServer Faces 1.2), and Jan Luehe (spec lead for JSR 245, Java Server Pages 2.1), discussing new JSF and JSP features in Java EE 5. the JSP and JSF common expression language, AJAX, and the role annotations play in dependency injection. If you're working with AJAX you've reduced bandwidth by sending just needed data as XML rather than requesting a whole new page--but are you making unnecessary requests? Bruce Perry says "Making HTTP requests willy-nilly from AJAX applications is almost never a good idea or design decision. The server side of the equation may not be able to handle the flood of requests. The client side of the AJAX application may have some of its requests time out or abort, which will disrupt the user experience that is meant to be AJAX's strength." In the xml.com article An AJAX Caching Strategy, Bruce shows how to tighten up your code. David Van Couvering explains The Synchronized Web in today's Weblogs: "James Governor of RedMonk coins a new term for web applications that can run online and offline and keep its data synchronized" In Tricks and Tips with NIO part I: Why you must handle OP_WRITE, Jean-Francois Arcand writes: "As promised at JavaOne, I will start discussing what I've learned when designing Grizzly, the HTTP front end of GlassFish. I will try to not restrict mu observations to Grizzly, but to NIO based server in general. For the first installment, I will discuss why handling the OP_WRITE operation-set bit." Brian Leonard has more details about Trying out JBoss' Seam (Continued): "In my previous blog entry I converted a standard JSF / EJB 3.0 application to one that uses JBoss' Seam framework. I covered Seam's primary feature, direct integration of JSF with EJB 3.0, eliminating the Managed Bean. In this entry, I'm going to show off Seam's validation support." In Projects and Communities, Carla Mott answers questions about GlassFish asked at JavaOne, with GlassFish BoF Summary. Among the topics raised: whether GlassFish is production-quality, will clustering be added to GlassFish, why does the project use TestNG instead of JUnit, and why should users switch to GlassFish? Robert Stephenson's blog Graduation Day, part I points out four graduations from the GELC incubator. "Two of the projects are in Portuguese and one is in Turkish, reflecting the "G" (for "Global") in GELC and the international nature of Java.net itself. " In today's java.net News Headlines :
