About This Tutorial

This tutorial is a beginner's guide to developing J2EE applications for the SunTrademarked Open Networking Environment (Sun ONE) platform. Here we cover all the things you need to know to make the best use of this tutorial.

Who Should Use This Tutorial

This tutorial is intended for programmers interested in developing J2EE applications using the Sun ONE platform. Specifically, it uses the Sun ONE Studio 4, Enterprise Edition for Java to develop J2EE applications and deploy them on Sun ONE Application Server 7.

---

Note: This release of the tutorial includes information on Web applications and Web services. A future release will add coverage of Enterprise JavaBeans technology and J2EE platform services such as transactions, security, resources, and connectors.

---

This tutorial is not a comprehensive introduction to Sun ONE platform software. It focuses on teaching the concepts of J2EE technologies through an extensive set of examples and provides basic instructions in how to use the software so that you can develop, configure, build, deploy, and run the examples. To learn how to use the software, see the resources listed in Further Information.

Prerequisites

To understand this tutorial you will need a good knowledge of the Java programming language, SQL, and relational database concepts. The topics listed in Table P-1 The JavaTrademarked Tutorial are particularly relevant:

About the Examples

If you are viewing this online, you need to download The J2EETrademarked Tutorial for the Sun ONE Platform from:

http://java.sun.com/j2ee/1.3/download.html#tutorial

Once you have unzipped the tutorial bundle, the example source code is in the <INSTALL>/j2eetutorial/examples directory, with subdirectories for each of the technologies. Note that <INSTALL> is the directory in which you unzipped the bundle.

To build the examples you need a copy of Sun ONE Studio 4 update 1, Enterprise Edition for Java. You download a free trial copy of this edition of Studio from:

http://wwws.sun.com/software/sundev/jde/index.html

To deploy and run the examples, you need a copy of Sun ONE Application Server 7, Platform Edition or Standard Edition. Sun ONE Application Server 7, Platform Edition is free for development and deployment, but does not allow remote management. Sun ONE Application Server 7, Standard Edition is free for development and evaluation and supports remote management. You can download either edition of the application server from:

http://wwws.sun.com/software/products/appsrvr/home_appsrvr.html 

To deploy the examples from Sun ONE Studio to Application Server 7, you also need to install the Sun ONE Application Server 7 Plugin into Studio. You can get the Plugin from the Studio Update Center or the Application Server 7 installation. SunTrademarked ONE Studio 4, Enterprise Edition for JavaTrademarked with Application Server 7 Tutorial contains information on how to install the Plugin.
