Introducing JBoss Remoting  With JBoss World 2005 a week away, JBoss has introduced a new remoting framework. Before you say "another one?" John Mazzitelli hopes you'll take a look at JBoss Remoting, which rids you of RMI-style skeletons and stubs, and offers flexibility and extensibility on both the client and server sides.   [ONJava.com]

On-Demand Stateful EJBs  EJB session beans can be stateful or stateless, but they can't easily change from one to the other. That can be a problem in certain business situations. Swaminathan Radhakrishnan has a pattern that he says can address this problem.   [ONJava.com]

Internationalization, Part 2  Having your Java apps run correctly both down the street and across the globe presents some hefty challenges. Part one of this two-part excerpt from Java Examples in a Nutshell, 3rd Edition covered the first two steps to internationalization in Java: using Unicode character encoding and handling local customs. This week deals with the third step in the process: localizing user-visible messages.   [ONJava.com]

Designing a Fully Scalable Application  It's difficult, maybe impossible, to know up front how much or in what ways your application will need to scale. But by decoupling parts of the application, you can at least ensure that the scaling process can be kept modular. Amir Shevat shows how some sharable pieces of the MantaRay messaging system can allow your app to grow beyond one box.   [ONJava.com]

JDMK and Legacy IT Management  Keeping a network with legacy (and possibly unreliable) devices is nearly impossible without some automated help. Stephen Morris shows how to use the Java Dynamic Management Kit to keep tabs on your network and find potential points of failure.   [ONJava.com]

Internationalization, Part 1  Writing software that is truly multilingual is not an easy task. In this excerpt from Chapter 8 of Java Examples in a Nutshell, 3rd Edition, author David Flanagan offers programming examples for the three steps to internationalization in Java: using Unicode character encoding, handling local customs, and localizing user-visible messages.   [ONJava.com]

Eclipse Plugins Exposed, Part 1: A First Glimpse  Many developers use Eclipse out of the box as an IDE, never investigating its powerful extensibility. But as Emmanuel Proulx shows in this first installment of a new series, Eclipse's modular system of plugins allow you to customize it to your suit your development needs.   [ONJava.com]

WS-Security in the Enterprise, Part 1: Problem Introduction  WS-Security doesn't exist in a vacuum--in an enterprise, it must work with many other systems, which means dealing with other access control systems and potential incompatibilities. Denis Pilupchuk begins his series on integrating WS-Security and enterprise systems by spelling out where the problem lies and what pieces need to be created to resolve it.   [ONJava.com]

Creating Varargs in Java 1.5 Tiger  This excerpt from Java 1.5 Tiger: A Developer's Notebook, by bestselling Java authors Brett McLaughlin and David Flanagan, shows you how to create and iterate over Java 1.5 varargs (variable-length argument lists). Learning to use varargs will have you writing better, cleaner, more flexible code in no time.  [ONJava.com]

Object-Relational Mapping with SQLMaps  Hibernate is great--if your DBA will let you run generated database queries on his or her system. Sometimes you need to keep the option of hand-optimized queries open. Sunil Patil introduces SQLMaps, a framework that allows you to do just that.   [ONJava.com]

Bitwise Optimization in Java: Bitfields, Bitboards, and Beyond  Flipping bits on and off is the lowest level of computing, and most Java developers are totally isolated from it. But maybe they shouldn't be. In this article, Glen Pepicelli introduces the idea of bitsets--ints and longs whose bitwise representation are the data you're interested in--and how they can be used with mathematical and logical operators to write faster code.   [ONJava.com]

IRC Text to Speech with Java  Paul Mutton creates a multi-platform IRC bot that uses the FreeTTS Java speech synthesizer library to convert IRC messages into audible speech. Why would you want to use an IRC text-to-speech system? By reading out messages as they arrive, you can keep working, diverting your attention to IRC only when necessary. Paul is the author of IRC Hacks. 

Internals of Java Class Loading  When are two classes not the same? When they're loaded by different class loaders. This is just one of many curious side effects of Java's class-loading system. Binildas Christudas shows how different class loaders relate to one another and how (and why) to build your own custom class loader.   [ONJava.com]

QuickTime for Java Components  In this excerpt from QuickTime for Java: A Developer's Notebook, Chris Adamson introduces QuickTime components and how they enable runtime discovery of available features, including importers and exporters for graphics and movie formats.   [ONJava.com]

An Introduction to Service-Oriented Architecture from a Java Developer Perspective  Service-oriented architectures offer a new way to think about building software applications, with coarse-grained pieces of functionality split out into "services" that communicate with standardized, widely understood interfaces like XML and SOAP. In this article, Debu Panda shows you how to design and connect SOAs.   [ONJava.com]

Software Infrastructure Bottlenecks in J2EE  Sometimes you can throw more CPUs and memory in a box and your web application doesn't get any faster. This can happen when the bottleneck is not in the hardware but the software; specifically, your application server. Deepak Goel looks at what this looks like in terms of performance characteristics and what you can do about it.   [ONJava.com]

Validating Objects Through Metadata  Metadata, in the form of J2SE 5.0's annotation, allow you to mark up your your code with declarative information, and then use reflection to pull out those annotations at runtime and use them. Jacob Hookom shows how these techniques can be used to validate input to your application.   [ONJava.com]

Build an eDoc Reader for Your iPod, Part 3  The availability of capable, open-source Java libraries makes it very tempting to call those libraries from otherwise native applications. But it's not always easy. In "Build an eDoc Reader for Your iPod, Part 3", Matthew Russell shows how he used a Java PDF library and Mac OS X's Cocoa-Java bridge to bring PDF support to his eDoc reader.  [MacDevCenter.com]

Parsing an XML Document with XPath  Pulling just a single node value or attribute from an XML document can be inefficient if you have to parse over a whole list of nodes you don't want, just to get to one you do. XPath can be much more efficient, by letting you specify the path to the desired node up front. J2SE adds XPath support, and the JDOM API also offers support through an XPath class. Deepak Vohra looks at both approaches.   [ONJava.com]

Streaming QuickTime with Java  Realtime multicast streaming came to QuickTime in version 5, but now, years later, it's not widely realized that it can be called from QuickTime for Java. Chris Adamson, author of QuickTime for Java: A Developer's Notebook, shows how it works.   [ONJava.com]

Mock Objects in Unit Tests  Unit testing your code against a service or process that's either too expensive (commercial databases) or just not done yet is something you can deal with by simulating the other piece with a mock object. EasyMock can suffice in some cases, but it can only create mock objects for interfaces. Mocquer, based on the Dunamis project, can create mocks for classes, too. Lu Jian shows how it works.   [ONJava.com]

Caching Dynamic Content with JSP 2.0  Server-side caching is a powerful and popular technique for improving the performance of server-side applications. After all, why compute twice what you can compute once and hang on to? Andrei Cioroianu shows you how to exploit this technique in JSP 2.0.   [O'Reilly Network]

Working with Hibernate in Eclipse  Jim Elliott was curious about whether anyone had written plugins to work with Hibernate in Eclipse, as he'd just finished writing Hibernate: A Developer's Notebook. It turns out there are several such efforts underway. In this article, Jim explores Hibernate Synchronizer--a plugin that automatically updates your Java code when you change your mapping document.   [O'Reilly Network]

ONJava 2004 in Review: Popular Articles  Editor Chris Adamson takes a look back at some of the most popular articles published on ONJava during the last year.   [ONJava.com]

Towards Bug-Free Code  Test-driven development sometimes sounds better than it turns out to be. Early decisions to tightly couple functional parts of your system can make it a lot less amenable to testing than it ought to be. As Ashwin Jayaprakash shows, J2SE 5.0's generics make working with abstract classes and interfaces easier than it used to be, which encourages loose coupling and facilitates testing.   [ONJava.com]

Generating an XML Document with JAXB  Among the positive aspects of XML Schemas is their support by the Java Architecture for XML Binding (JAXB). In this article, Deepak Vohra shows how JAXB can help convert a schema-supported XML file to a regular Java object and back again.   [ONJava.com]
