RDF is increasingly recognized as an excellent choice for representing and processing semi-structured data. In this article, Web developer Philip McCarthy shows you how to use the Jena Semantic Web Toolkit to exploit RDF data models in your Java applications.

The Jakarta Element Construction Set (ECS) is an open source project for creating markup language documents using the Java language and an object-oriented approach. Java developer Amit Tuli provides an introduction to ECS and shows you a step-by-step approach for using it to generate well-formatted status reports from log files. You will create a sample application to help you better understand ECS and its usage. You'll also learn some other potential uses for the API.

The IBM Reflexive User Interface Builder (RIB), a new technology available from alphaWorks, is an application and toolkit for building and rendering Java AWT/Swing and Eclipse SWT GUIs. RIB specifies a flexible and easy-to-use XML markup language for describing Java GUIs and provides an engine for creating them. You can use RIB to test and evaluate basic GUI layout and functionality, or to create and render GUIs for an application.

Learn how to create digital-certificate chains to test your software. IBM Software Engineer, Paul H. Abbott, clarifies this seldom-documented process by showing you how to use the freely available OpenSSL toolkit to create a certificate chain of any length. He also describes common certificate attributes and shows you some sample Java code for reading the certificates you create into a Java keystore.

The On Demand Operating Environment is based upon the concepts of Service Oriented Architecture (SOA). SOA views every application or resource as a service implementing a specific, identifiable set of (business) functions. In addition to the business functions, services in an on demand environment might also implement management interfaces to participate in the broader configuration, operation, and monitoring of the environment. This article provides an introduction to the On Demand Operating Environment.

Tuning isn't always about speed, sometimes other aspects of the application need fixing. When your application needs tuning, your first course of action is normally to monitor the application with a profiler. But profiling is not always practical -- sometimes for ironic reasons. In this installment of Eye on performance, Jack Shirazi and Kirk Pepperdine, Director and CTO of Java Performance Tuning relate their recent experiences with profiling a fat client -- so fat, in fact, that it left no room for a profiler.

JRuby combines the object-oriented strength of Smalltalk, the expressiveness of Perl, and the flexibility of the Java class libraries into a single, efficient rapid development framework for the Java platform. In this third installment in the alt.lang.jre series, Michael Squillace and Barry Feigenbaum introduce JRuby, a sophisticated addition to your Java development toolbox.

This article introduces the TableModel Free (TMF) framework which eliminates the need to use TableModels with Swing JTables. The TMF framework allows for more configurable JTables by moving all of table-specific data outside of the compiled code and into a configurable XML file. Framework developer and Java UI enthusiast Michael Abernethy walks you through TMF framework, helping you reduce the size of a TableModel from hundreds of lines of code to just a single line, making management a snap.

Multithreading and concurrency are nothing new, but one of the innovations of the Java language design was that it was the first mainstream programming language to incorporate a cross-platform threading model and formal memory model directly into the language specification. While this simplifies the development of platform-independent concurrent classes, it by no means makes writing concurrent classes trivial -- just easier.

Learn how to use JXTA technology to integrate thin Java 2 Platform, Micro Edition (J2ME) clients into enterprise-scale messaging applications by developing a set of classes that let you integrate J2ME clients into JMS (Java Message Service) applications running on Java 2 Platform, Enterprise Edition (J2EE) servers.

This tutorial introduces the Hello World program to new Java programmers using the JOptionPane interface.

A guide to the use of conditionals in Java, covering if statements, else statements, else if, as well as switches.

The Java language, and the ever-growing Java platform, have revolutionized programming. The goal of this tutorial is to introduce you to the Java syntax you're most likely to encounter professionally, and to expose you to idioms that will help you avoid trouble. Follow along with Java professional Roy Miller as he guides you through the essentials Java programming, including the OOP paradigm and how it applies to Java programming; Java language syntax and use; creating objects and adding behavior, working with collections, handling errors; and tips for writing better code.

Explains operators and simple mathematical functions, which operators take priority over others, and how to implement them in code.

Web apps developed with the thin client computing model exhibit performance gaps and user interface limitations. As an alternative, the IBM FacesClient Components (formerly called the Odyssey Browser Framework) provides a more effective model for developing Web apps. FacesClient Components work inside a portlet programming environment to deliver exceptional value in the form of richer user interfaces and improved performance.
