At the same time, a bewilder- ing variety of technologies and products has been introduced, all jostling for recognition and market share. We decided to write this manual on the basis of two considerations: one technical and one human in nature. The technical consideration was that the alignment of JSP 2.1 and JSF 1.2 achieved with Java Platform, Enterprise Edition 5 (Java EE 5), and the subsequent release of Servlet 2.5 and Tomcat 6, had finally realized full consistency across the whole platform. The human consideration was that, although a lot of information and documentation is available by searching the Web, there is a need for a compendium capable of taking a reader through all the steps necessary to build a Java-based web application. In our endeavor to cover all the subjects you’ll need, we have included chapters dedicated to HTML, JSP, databases, JSF, Tomcat, and XML, and sections on Java and HTTP. We’ve also touched on Cascading Style Sheets (CSS), JavaScript™, Asynchronous JavaScript and XML (Ajax), and Simple Object Access Protocol (SOAP) and provided detailed references for HTML, JSP, JSF, and SQL. This is a practical manual driven by examples rather than by abstract con- cepts. Nevertheless, we have consistently justified and explained every step taken and every choice made throughout the book. You’ll also discover useful tips and tricks to make your programming life easier. If you keep coming back to this book to look up techniques and to check out options and features, we will have achieved our goal. Happy programming!
