Chapter 9: J2EE Application Deployment

Overview

Deploying J2EE applications requires an understanding of J2EE components and configuration. It's important to understand what components exist within a J2EE application and how they're packaged into a deployment file. Using this information you can package the application by modifying the corresponding configuration file (deployment descriptor). Once the application has been packaged into the correct EAR file, it's deployed to the server.

In this chapter, we'll cover the following:

• J2EE architecture. Identify the architecture and components within a J2EE application.

• Configuration. Identify what files are configured for an application deployment using deployment descriptors.

• Organization and packaging. Identify the structure and purpose of the JAR, WAR, and EAR files.

• Deployment. How to deploy J2EE applications and what actually happens during an application deployment.
