The J2EE 1.4 Tutorial
|
The J2EE 1.4 platform is quite large, and this tutorial reflects this. However, you
dont have to digest everything in it at once.
This tutorial opens with three introductory chapters, which you should read
before proceeding to any specific technology area. Chapter 1 covers the J2EE 1.4
platform architecture and APIs along with the Sun Java System Application
Server Platform Edition 8. Chapters 2 and 3 cover XML basics and getting
started with Web applications.
When you have digested the basics, you can delve into one or more of the four
main technology areas listed next. Because there are dependencies between
some of the chapters, Figure 1 contains a roadmap for navigating through the
tutorial.
The Java XML chapters cover the technologies for developing applications
that process XML documents and implement Web services components:
The Java API for XML Processing (JAXP)
The Java API for XML-based RPC (JAX-RPC)
SOAP with Attachments API for Java (SAAJ)
The Java API for XML Registries (JAXR)
The Web-tier technology chapters cover the components used in developing the presentation layer of a J2EE or stand-alone Web application:
Java servlets
JavaServer Pages (JSP)
JavaServer Pages Standard Tag Library (JSTL)
JavaServer Faces
Web application internationalization and localization
The Enterprise JavaBeans (EJB) technology chapters cover the components used in developing the business logic of a J2EE application:
Session beans
Entity beans
Message-driven beans
Enterprise JavaBeans Query Language
The platform services chapters cover the system services used by all the
J2EE component technologies:

After you have become familiar with some of the technology areas, you are
ready to tackle the case studies, which tie together several of the technologies
discussed in the tutorial. The Coffee Break Application (Chapter 35) describes
an application that uses the Web application and Web services APIs.
