Getting started with the FMA and Jiro
If you're looking for a unique programming challenge, try your hand at building a management application for a distributed, cross-platform network. This article is the first in a three-part series that looks at how Sun Microsystems's Jiro technology and the Distributed Management Task Force's Web-Based Enterprise Management Initiative (WBEM) can simplify the creation of management applications for heterogeneous environments.

Faster apps on a better machine
If you want to build and run faster Java applications on the IBM Developer Kit for Linux, version 1.3, roll up your sleeves and prepare to get dirty. This article provides hands-on instruction for profiling, monitoring, and performance tuning not only your IBM Developer Kit, but your hardware capacity, the Linux 2.2.x kernel, and your Java applications.

Diagnosing Java Code: The Liar View bug pattern
GUIs are generally designed with a model-view-controller architecture in which the view is decoupled from the model. The separation presents a challenge to automated testing because it's difficult to verify that a state change in the model is reflected appropriately in the view -- it spawns the infamous "Liar View." This installment of Diagnosing Java Code examines the Liar View bug pattern.

Build your own Java-based supercomputer
If you've ever wanted to build your own supercomputer but have been held back by the demands of parallel programming in C, Pseudo Remote Threads is for you. This prize-winning Java programming model greatly simplifies parallel programming on clusters, bringing supercomputing out of the laboratory and into the hands of everyday Java programmers. Article includes code snipets.

Creating a text adventure game in Java
This is a series of tutorials that show you how to create an object-orientated adventure gaming system.

Secure communication between peers: SSL through JSSE
A core requirement of any non-trivial P2P application is secure communication between peers. While the details of the security depend on how the application will be used and on what it will protect, it's often possible to implement strong, general-purpose security using off-the-shelf technology such as SSL. This article demonstrates how to use SSL (via JSSE) in P2P security.

A three-pronged solution for identifying users
The problem of system security starts with discovering the identity of the user on the other end of the communications link. This article discusses three familiar approaches for identifying users, highlights their strengths and weaknesses (alone and in combinations), and provides some examples of each.

Swing's new JFormattedTextField component
Accepting formatted input doesn't have to be difficult with input verifiers and focus listeners. This installment of Magic with Merlin shows you how to use the new JFormattedTextField component to prompt for numbers, dates, and formatted input. The Java 2 Standard Edition (J2SE), version 1.4, adds two new Swing components to the palette of available GUI elements: JSpinner and JFormattedTextField.

Intelligent data keeps Swing simple
This generic Swing architecture eases your UI development by integrating intelligent data with Swing components. You can use the iData architecture to create a central repository of data within your application. By doing so, you'll more fully separate data from presentation and produce code that's cleaner and easier to maintain. This article explains how to use the iData technique to ease complex GUI development.

Swing's new Spinner component
This new column offers a glimpse into the new Java 1.4 release, starting with the new jSpinner component of Swing, which lets users easily select a date, number, or choice from a pick list. Article includes code snipets.

Java 2 Micro Edition (J2ME) Application Development : MIDP Programming.
Sample chapter from "Java 2 Micro Edition (J2ME) Application Development" on Mobile Information Device Profile programming.

WAP builds Java applications
If your company already relies on multitiered enterprise Java applications, then you may be closer to a wireless future than you think. By outlining a sample application, this article shows you how to connect your existing enterprise Java infrastructure to a wireless network with minimal investment in equipment and labor. Using existing EJBs, modified servlets, and new WML and WMLScript pages makes the process a snap.

Tip: Set up SAX Parsers
This is the first in a series of tips that will serve as a comprehensive guide to using XML from the Java programming language. I begin with coverage of the SAX API. This tipreviews getting an instance of a SAX parser and setting various features and properties on that parser.

XML generation with JAVA
XML developers used to rely on XML parsers to read XML files. They also used to rely on XML processors to transform XML to *ML (HTML, XML, etc.). However, most of them forget these tools to generate XML from scratch. They should not. This article presents code samples for generating XML with JAVA/JAXP.

Long-term persistence: Serialize JavaBean component state to XML
The ability to save the JavaBean component state for long-term persistence within an XML document has been a topic of much discussion with Java developers in the past few years. This feature has finally been adopted in the 1.4 version of J2SE. This article shows you how to use the new XMLEncoder and XMLDecoder classes, bypassing serialization and allowing you to generate fully initialized bean instances.
