In the last chapter we introduced you to web applications, but the web tier is just one part of the J2EE spectrum. In this chapter, we'll expand the JAW application from a simple WAR file into a full-fledged EAR. We'll explore the different parts of an EAR file. We'll build a Common JAR containing classes that can be shared across all tiers of the application. Finally, we'll play with various Ant and XDoclet tasks to create our EAR and dynamically generate the deployment descriptors JBoss needs. |
