This book is a hands-on guide to the technologies used to develop Web Applications and Web Services. This includes the set of technologies known as Java 2 Enterprise Edition (J2EE), and the emerging set of technologies for developing Web Services known as the Java APIs for XML (JAX). The book begins with a sample application that has only a command line user interface, runs on a single system, has no persistence mechanism for its data, and has not facility to interoperate with other programs. In gradual step-by-step evolution, this application grows to a rich user interface with a web-centric architecture using Servlets, JSP, and XML. The book explores persistence options including Serialization, JDBC, and Java Data Objects. It also shows how Enterprise JavaBeans can be used to deploy the application in an Application Server. The book is very code-rich, with example programs throughout and on the CD. The book assumes only a basic knowledge of Java programming; all of the fundamental technologies you need to know, such as XML, Servlets, and Enterprise JavaBeans, are covered in a logical progression.
