Before you can work with J2EE 1.4 SDK, you need to make sure it is set up correctly. This article, the first of two parts, will help you do that. The second part will take you through writing a simple application. It is excerpted from chapter two of the book Beginning J2EE 1.4 From Novice to Professional, written by James L. Weaver, Kevin Mukhar, and Jim Crume (Apress, 2005; ISBN: 1590593413).
Since this is a book for developers by developers, you'll get the most from this book by running the examples and experimenting. This chapter will help you to make sure that youve properly installed the J2EE 1.4 SDK and will walk you through the steps of setting up the environment and writing a simple application. This is vital to ensuring that you don't encounter needless frustration as you work through the examples. You'll also get a taste of the essential steps of creating a J2EE application, what those steps do, and why they're needed.
In this chapter, you will learn:
What the exact prerequisites for installing the J2EE 1.4 SDK are, and how to configure your system to run enterprise Java applications
How to construct a simple JSP application, and how to deploy and run this application
Even if you already have your environment set up, it's probably a good idea to read through the development steps in this chapter not only to ensure that your environment is set up correctly, but also to give you some essential insight into the fundamentals of building a J2EE application.
