Part 1: A WebSphere Perspective


Chapter List

Chapter 1: Introduction to WebSphere
Chapter 2: The WebSphere Programming Model
Chapter 3: WebSphere Development Tools

This book is divided into four parts, each with a story to tell.

One of WebSphere's primary objectives is to put you back in the business of writing business functions that add value to your business; that enable a high return on your investment in application development; and that help you sustain the value of the investment. WebSphere is intended to hide, or at least reduce, the complexity of information systems by abstracting the computing infrastructure from the application-programming model. This enables you to build efficient and durable application functions that address your business concerns. WebSphere incorporates a substantial arsenal of techniques and component facilities to address a broad range of scenarios and computing concerns.

The first part of this book is designed to create a view of the landscape that we call WebSphere. We won't teach you how to program WebSphere in this part, but we will help you put WebSphere in perspective. We will introduce you to the set of business problems that WebSphere can help you with. We will sort out some of the jargon that IBM typically uses when talking about WebSphere, and why WebSphere is so much more than just an application server – although, it is that too. You will understand the packaging philosophy, the programming model, and tool support for WebSphere, and how it addresses a huge range of computing needs – both in terms of scale and sophistication.

This part will help you understand the major pieces of the programming model and how they fit together. WebSphere has a soul that gets its energy from the Java language, but WebSphere has given that energy form and utility – enabling you to leverage its power to make your business more productive and competitive. As with all powerful machines, it is good to understand something about how all the parts work and their use. This survey of the programming model will help orient you; to prepare you for the more in-depth programming information you will receive through the rest of the book.

Harnessing the power of WebSphere is made easier if you have the right tools. We will introduce you to the WebSphere Studio tools because the rest of the book relies on this knowledge when explaining important programming concepts; more importantly we need to convince you that using such a tool is critical to your programming productivity. If you're still using vi and make for building applications, consider moving into the 21st century – you won't look back.

Having completed this part, you will be equipped to maximize your use of the programming information we provide in the subsequent sections.
