Data Wizard for Java is a tool for building a simple graphical user interface (GUI) that makes it easy to collect necessary data. This tool enables the building of data wizard applications using only a scripting scenario in an XML format. Data Wizard for Java can help to produce a GUI by using a simple script to describe the necessary input parameters and the required tools or utilities to be called.
Web Services for DB2 Cube Views provide access to multidimensional data stored in DB2. These Web services allow a client application to read data from the cubes and perform basic online analysis on multidimensional data and metadata through the Web, using XPath and XML.
JSP technology is well-known, supported by most application servers, and endorsed by the J2EE Blueprints. Why would you choose otherwise? In this first of a two-part series, learn about the Tea template language and how Tea can be a viable alternative to JSP technology.

This article takes a new look at UPC symbols and bar codes, and describes how you can use Java to read information from a UPC bar code. The authors explain how to expedite and organize your enterprise operations that revolve around an IBM DB2 database. The sample application described in the article includes downloadable code.
Add more versatility to your existing Java framework. The same framework supports file access, network access, character conversion, compression, encryption and so forth. This article presents a framework that lets an application efficiently read data from a source that only supports writing data to an output stream.
Examine the roots of the double-checked locking idiom, why it was developed, and why it doesn't work. The Java programming language contains several useful programming idioms. It also contains some that further study has shown should not be used. Double-checked locking is one such idiom that should never be used.

Ant, from Jakarta project at the Apache Foundation, has become a de facto standard for building Java projects. You may already be using it to create automatic builds. It's easy enough to tailor those builds to your needs by customizing the build files; but what if you want to wait until run time to set certain properties? This article shows you how to extend Ant to produce builds that are interactive at run time; users can follow prompts to change parameters each time they conduct a build without having to deal with unfamiliar build files. You can incorporate this functionality into your builds to provide a smoother and more flexible experience for your end users.

The Java 2 Platform, Micro Edition (J2ME) offers great tools for developers, porting the Java platform's network-centric and platform-agnostic worldview down to memory- and processor-limited devices. This article explains the basics of the J2ME world, showing you the building blocks of the platform and demonstrating a sample application.

Glass box extensibility refers to the ways in which a software system may be extended when the source code is available for viewing, but not for modifying -- it lies as the happy medium between black box design (in which extensions are built without viewing the original code) and open box design (extensions are coded directly into the base code). Because the new extensions are based directly on the original code but don't alter it, the glass box design is probably the most effective, and safest, method of extending a software system. This article expands on the topic of glass box extensibility touched on last month in this column. After reading this article, you'll know when to use the glass box and will have some tips on how to implement it.

Java 2D may be the most obvious solution for programming 2D graphs in Java programs, but it's not the only one. This article proposes an elegant alternative in the form of Java Objects for Science (JSci), an open-source package that lets you create 2D bar graphs, pie charts, and line graphs in Swing.

One of the strengths of the Java platform is its object-oriented nature; one of the benefits of object-oriented languages is that they aid code reuse. But what if you're a Java programmer and you want to reuse code that wasn't written in the Java language? With Bridge2Java, an IBM alphaWorks technology, Java developers can integrate COM objects into their applications. This article explains how it works.

Project Jxta is a community-run attempt to build a utility application substrate for peer-to-peer applications. The initial reference implementation of Jxta includes a command-line shell that allows experimentation with the core Jxta platform without programming. This article takes us through a hands-on tour of the <a href="http://www-106.ibm.com/developerworks/java/library/j-p2pint2?open&l=766,t=grj,p=Jxta2">Jxta shell</a>. You'll explore its command set and extend its capability by writing your own custom commands using the Java programming language.
Web services and J2EE connectors promise to simplify the integration of heterogeneous enterprise information systems and provide a way for business partners to share their respective applications' functionality over the Internet. This article uses an insurance broker scenario, in which the programmatic functions from legacy transactions are incorporated into a Web application, to illustrate these capabilities.

Graphical and user interface capabilities have progressed in leaps and bounds since the early days of the Java language. The Java 2 platform contains a sophisticated cross-platform user interface architecture that consists of numerous high-level components, an advanced feature-rich device-independent graphics system, and a host of multimedia extensions. This article explores this progression, examines the capabilities of the current version 1.3 in detail, and looks to the future to see what release 1.4 will offer.
Neural nets may be the future of computing. A good way to understand them is with a puzzle that neural nets can be used to solve. Suppose that you are given 500 characters of code that you know to be C, C++, Java, or Python. Now, construct a program that identifies the code's language. One solution is to construct a neural net that learns to identify these languages. This article discusses the basic features of neural nets and approaches to constructing them so you can apply them in your own coding.
This article shows you how to combine and leverage the best parts of Jiro technology and the Web-Based Enterprise Management (WBEM) initiative. Using familiar examples from the previous two articles of this column, this article introduces the WBEM client technologies for accessing and manipulating data in a CIMOM. It then shows you how to access the same data more elegantly and efficiently, by rearchitecting the Jiro management facade to act as the interface to the CIMOM. Finally, he talks about the need for greater standardization of Jiro management facades and discusses the future of management application programming under a combined Jiro and WBEM development platform.
In the real world of everyday computing (and development), there are many situations where "whipping up a Java program" to perform a task is either impractical or too time consuming. This article takes you into the underground world of FESI (Free EcmaScript Interpreter), where deploying the Java language in a quick-and-dirty fashion is the norm rather than the exception. Article includes code snipets.
This article leads you into the gray zone between modeling and method, with a look at requirements gathering via use case modeling. In particular, this article focuses on the relationship between user interfaces, system interfaces, and use case descriptions.
