Patterns for e-business
The paths to creating e-businesses are repeatable. Many companies assume that they are unique and that therefore very creation of an e-business has to be learned as you go. While this may be encouraged by some service providers and programmers (because it is both profitable and allows programming artistic flair), IBM has learned that in fact, there are lessons and architectural paths or patterns that can be discerned from all these engagements. Whether your company is a startup or has extensive legacy applications, these patterns allow you to reuse existing technologies so that your projects can be completed quickly.

The OO design process: Getting started
Welcome to the first installment of this online class. My intent with this column is to provide a detailed experience in the object-oriented (OO) design and development process by actually having you do it. This column is more of a journey than an event, as it will take months to get through the entire process. We'll start out with requirements gathering, move through analysis to design, then do a Java implementation of that design. When we're finished, you'll have a complete case history of an OO program, literally from start to finish. I'll talk a lot about the underlying theory, but the central focus will be real examples of how that theory is applied.

The Tao of e-business services
The concept of Web services is the beginning of a new service-oriented architecture in building better software applications. The change from an object-oriented system to a service-oriented one is an evolutionary idea that sublimated from the global Internet and Web system. To understand how to build Web Services into your computing architecture, you need to carefully understand the role they play. This article details the software engineering concepts behind the Web Services architecture, how it has evolved, how it is structured, and how it can be brought into your existing computing infrastructure

Creating target-rich environments in a service-oriented architecture
This article introduces and encourages the use of taxonomies for categorizing services in ways that make them easy to locate. We begin by describing the problem addressed by taxonomies and then introduce a scenario that requires one. We discuss the need for taxonomies from the perspective of service providers and requestors. We then create the requirements for an architecture to support categorization and a proposal on how this architecture will address these needs.

DeveloperToolbox Technical Magazine: Understanding and using Java Sound API sampled audio
Enhancements to the Java Sound API in Sun Java 2 version 1.3 have drastically improved the audio capability of the Java platform. Since Sun Java 1.02, users have always been able to enable some sort of sound. However, it was always through the limited sun.audio application programming interfaces: the AudioClip or the AudioDataStream. This support consisted of playing or looping a simple AU format file. Java audio improved somewhat in Sun Java 2 version 1.2 with the ability to play new file types; but, once again, users were limited in the public Application Programming Interface (API) to manipulate the sounds. The Java Media Framework (JMF) provides better programmatic control of the sound, but this framework is a Java extension and not available in every Java platform. Finally, with the Java Sound API as a standard part of Sun Java 2 version 1.3, users have both a robust feature-laden sound engine and the public programming interface to use it. Simple things such as finding the length of a sound or listening for the end of a MIDI stream now are possible. This article gives you an understanding of the Java Sound API architecture, an explanation of the key classes to this sound engine and several programming examples that explain how to put sound into your Java programs.

Transforming legacy applications with Web Services
Like the blind men and the elephant, answers about what Web Services is composed of depend on the focus of the problem domain. Simply put, Web Services is a means to publish application services in a well-known place, find services that meet the needs of a client, bind to those services, and invoke and use the services with standardized messages. In this article, we introduce Web Services, discuss legacy application and architectural issues, and demonstrate a sample application with the IBM XML and Web Services Development Environment toolkit.

Best Practice: WebSphere plug-in configuration regeneration
For a Web server to direct servlet requests to a servlet container on the application server, certain plug-in configuration files must be set correctly. If updates to the WebSphere Application Server configurations are made, the WebSphere Application Server must be stopped and restarted or manual regeneration of the plug-in config files must occur so that the plug-in can direct servlet requests correctly. In most large production sites, it is best to manually create the Web Server plug-in. There is a WebSphere property that allows you to disable automatic regeneration of the config files, but you must understand the implications of doing so.

Best Practice: Classpath structure for WebSphere Application Server
The WebSphere Application Server static system classpath structure is designed for stable packages that the application server uses frequently. The static system classpaths are searched first, followed by the dynamic classpaths. There are two different types of dynamic classpaths: Web Application classpath and Node Dependent classpath. The dynamic classpaths are structured to reflect packages that are subject to change. Classes that are stable and do not frequently change should be placed in the static classpath, whereas classes that are frequently changed should be placed in the dynamic classpath.

Best Practice: Designing applications with EJBs
When designing applications and considering the use of Enterprise JavaBeans (EJBs), you can choose from a number of options. These options offer different levels of complexity, advantages, and disadvantages. Based on the Model-View-Controller (MVC) architecture, a session bean can be used as a facade to an entity bean, providing increased performance by reducing the number of network calls. Besides performance improvements, the facade session bean hides the complexity of EJBs leading to separation of presentation logic and business logic.

Best Practice: Using java:comp and the DB2 Connect Gateway for portable database applications
Many WebSphere applications must access a DB2 database. When developing for WebSphere on zOS, the typical development scenario involves developing and unit testing an application in WebSphere Studio Application Developer and then redeploying to WebSphere Application Server for z/OS and OS/390. When the deployed application being developed must access data in a DB2 for zOS database, it is imperative that the development tool also access the database data on the zSeries machine. The best practice is to use the java:comp notation for accessing the DB2 datasources along with the DB2 Connect Gateway rather than hardcoding the database name and having to make changes when moving the application into production. Following this best practice will ease deployment to multiple platforms

XML Matters: Intro to PYX
XML is a fairly simple format. It uses plain Unicode text rather than binary encoding, and all the structures are declared with predictable-looking tags. Nonetheless, there are still enough rules in the XML grammar that a carefully debugged parser is needed to process XML documents -- and every parser imposes its own particular programming style. An alternative is to make XML even simpler. The open-source PYX format is a purely line-oriented format for representing XML documents that allows for much easier processing of XML document contents with common text tools like grep,sed, awk, wc, and the usual UNIX collection.

Best Practice: Developing Web applications for WebSphere Simple Configuration Runtime
When developing Web applications for deployment on the WebSphere Simple Configuration runtime, be mindful of possible future deployments on the WebSphere Standard Configuration runtime. Even though your Web application is not targeted to execute in a J2EE Server (like WebSphere Application Server 4.0.1 Standard Configuration), developers can adopt techniques that will make their code easier to maintain today and simpler to move to a more advanced runtime in the future. If a Web application is developed solely for the WebSphere Simple Configuration runtime, an application may have to be re-designed for deployment on a fully compliant J2EE Server.

Best Practice: Considerations for establishing test and production environments for WebSphere Application Server for z/OS and OS/390
Most customers establish several levels of application environments to provide isolation between test, production and other environments. This goes for WebSphere Application Server for z/OS and OS/390 installations as well. It is possible to create an environment with complete isolation between test and production by setting up separate sysplex environments for WebSphere Application Server, but not every customer has the ability to deploy as much resource as that implies. This document covers some of the key points to consider before deciding to configure WebSphere for zOS installation.

Best Practice: Using java:comp to locate EJBs and increase application portability
If you deploy the same J2EE application on multiple application servers
with a shared JNDI namespace, problems will occur as JNDI names in a namespace
must be unique. J2EE applications deployed in the WebSphere Application Server
environment should use the java:comp/env environment naming context (ENC) to
lookup EJBs and not use the JNDI name. With this naming context, conflicts
will be avoided and applications will be much more portable.
