Writing Enterprise Applications with Java 2 SDK, Enterprise Edition | This tutorial introduces you to the APIs, tools, and services provided in the Javaä 2 Enterprise Edition (J2EE) Software Developer Kit (SDK). You can get the free J2EE SDK (http://java.sun.com/j2ee/download.html) to use for demonstrations, prototyping, educational use, and verifying J2EE application portability. To support these uses the J2EE SDK comes with J2EE development and deployment tools, a Web server, Cloudscape database, Java Software application server, Extensible Markup Language (XML) support, the J2EE APIs, and Java Plug-In. Java Plug-In lets you run Java 2 applets in browsers that support an earlier release of the Java Runtime Environment (JRE).

This lesson introduces you to J2EE applications programming, and the J2EE SDK by showing you how to write a simple thin-client multitiered enterprise application that consists of an HTML page, servlet, and session bean. The J2EE SDK is a non-commercial operational definition of the J2EE platform and specification made freely available by Sun Microsystems for demonstrations, prototyping, and educational uses. It comes with the J2EE application server, Web server, database, J2EE APIs, and a full-range of development and deployment tools. You will become acquainted with many of these features and tools as you work through the lessons in this tutorial.
