Web Development with JavaServer Pages

Web Development with JavaServer Pages will teach you how to create dynamic content-personalized, customized, and up-to-the minute content-a key ingredient of site development on the World Wide Web today. JavaServer Pages (JSP) is a new server-side Java technology for generating dynamic content in web pages and other on-line applications.

This book covers all aspects of JSP development, as well as comparisons to similar dynamic content systems such as CGI, Active Server Pages, Cold Fusion, and PHP. It clearly demonstrates the advantages offered by JSP as a full-featured, cross-platform, vendor-neutral technology for dynamic content generation.

Web Development with JavaServer Pages focuses on the use of component-centric design via Java Beans and custom tag libraries for separating the presentation of dynamic data from its implementation. As such, JSP brings important benefits to both web designers, who focus on presentation, and web programmers, who focus on implementation, yielding improved division of labor and increased productivity.

Introduction

This chapter covers

JavaServer Pages technology and how it works
The evolution of dynamic content technologies
The benefits of using JSP for dynamic content generation
How to separate presentation and implementation

Welcome to Web Development with JavaServer Pages. This book has been written to address the needs of a wide audience of web developers. You may have only recently heard about this exciting new technology for developing dynamic web content, or perhaps you have already begun to use JavaServer Pages in your own projects. You may be a HyperText Markup Language (HTML) designer with little or no back-ground in programming, or a seasoned Java architect. In any case, this book will show you how to use JavaServer Pages to improve the look and maintainability of dynamic web sites and web-based applications, and ease the design and development process. So, without further ado, let's begin our look at JavaServer Pages.

What is JSP?

JavaServer Pages - JSP, for short - is a Java-based technology that simplifies the process of developing dynamic web sites. With JSP, web designers and developers can quickly incorporate dynamic elements into web pages using embedded Java and a few simple markup tags. These tags provide the HTML designer with a way to access data and business logic stored inside Java objects without having to master the complexities of Java application development.

Think of JSP as a type of server-side scripting language, although, as we'll see later, it operates quite differently behind the scenes. JavaServer Pages are text files, usually with the extension .jsp, that take the place of traditional HTML pages. JSP files contain traditional HTML along with embedded code that allows the page designer to access data from Java code running on the server. When the page is requested by a user and processed by the HyperText Transport Protocol (HTTP) server, the HTML portion of the page is passed straight through. The code portions of the page, however, are executed at the time the request is received, and the dynamic content generated by this code is spliced into the page before it is sent to the user. This provides for a separation of the HTML presentation aspects of the page from the programming logic contained in the code, a unique benefit we'll consider in detail below.
