Chapter 1 Introducing Jaguar CTS

J2EE platform support

Jaguar implements the Java 2 Enterprise Edition (J2EE) specification, with support for EJB 1.1 components, J2EE applications, J2EE Web applications, and the JavaMail electronic mail API.

"Component support"describes Jaguar's supported component models, including EJB.

A Web application is a unit of deployment for interrelated Web content, JavaServer Pages (JSPs), and Java servlets. The Web application contains static files, servlet and JSP implementation classes, and a deployment descriptor that describes how the files, servlets, and JSPs are configured on the host server. See Chapter 22, "Creating Web Applications" more information.

J2EE applications allow you to group related EJB 1.1 components and Web applications into a single entity. In this way, you can deploy related business logic components, Java servlets, Java Server Pages, and Web pages as a single unit between servers. Using the J2EE Application Client model, you can create clients that call the components and Web pages in the application. For more information, see these chapters:

J2EE application deployment from PowerJ PowerJ provides an integrated environment for developing EJB 1.1 components, Java Servlets, JSPs, and Web applications and deploying them to Jaguar as a J2EE application. See the EAServer Feature Guide for more information on using PowerJ with Jaguar.

The JavaMail API provides a standard Java interface to the most widely-used Internet mail protocols. See Chapter 30, "Creating JavaMail" for more information.

J2EE features require JDK 1.2 You must the JDK 1.2 version of Jaguar server if using any J2EE features.
