David Herron wrote a blog post inspired by an old C|NET article from October, 1997, which listed Java as one of 10 technologies at the time that "didn't stand a chance." Herron and the article he references point out that Java has apparently always been dying for quite some time and yet... somehow it keeps thriving. As Herron notes, news of Java's death have been greatly exaggerated.... more »

Do you ever get the feeling there's something not quite right about Swing threading? John Zukowski puts his finger on it in this article. While tracing Swing's single-threaded event model from Java 1.0 to its origins in the JavaBeans component model and AWT, he reveals an initialization bug in a commonly used start-up pattern.... more »

Standard Java has some deficiencies that make it less than ideal in the real-time world (see Sidebar 1. What Is Real-Time?). For one, the garbage collector (an internal JVM thread that reclaims old objects to free space on the heap) can run at any time, for any length of time, thereby introducing latency and non-determinism to your application. However, the garbage collector (GC) is not the only culprit in a standard Java application. The just-in-time (JIT) compiler, which optimizes your Java code for the machine it's running on, can be invoked at any time, even for code that has previously been optimized (JIT-compiled).... more »

The Apache Geronimo team has successfully implemented the exciting new Java™ Platform, Enterprise Edition (Java EE) 5.0 specification. One of the many notable features of Java EE 5 is the new Java Standard Tag Library (JSTL) 1.2 specification. The key to JSTL 1.2 is the unified expression language, which lets you use the best features of JSTL alongside the JavaServer Faces (JSF). In this installment, the renegade covers the importance of JSTL 1.2 by examining the history of Java Web technologies and how the Geronimo team has leveraged the GlassFish JSTL 1.2 implementation to add JSTL 1.2 support to Geronimo.... more »

PHP is a top Web development language, and Java™ technology is popular for business application development. Thus, to use the strengths of each language on the AIX® Version 5.3 operating system, the PHP Java Bridge has been developed. This series shows AIX 5.3 developers how to integrate both PHP and Java technology in their Web application development.... more »

Two new node types have been added to Groovy's SwingBuilder (and as a consequence SwingXBuilder and JideBuilder, if you grab a current snapshot): bind(...) and animate(...). These two features don't add new widgets, but a new orthogonal functionality, namely to update properties as other properties are changed, and to update properties over time.... more »

Since I've been studying the Rails framework, I've had an interest in integration with Java. Yes, JRuby is one possible solution, but if you have some large Java system that you want to integrate with, it' unlikely that you're just going to get the jar files to access that system's APIs. More likely is that system will expose itself as a service, and the service type du jour is REST.... more »
