This discussion begins with deploying servlets and JSPs; in other words, getting them running on Tomcat or WebLogic, either alone or as part of a web application.

This is what deployment is all about with web-related software: placing the software into service within a web container like Tomcat or an application server such as BEA WebLogic Server 7.0. The following recipes detail deployment of servlets and JSPs on these web containers, first individually, and then as part of a web application.

The wonderful open source Jakarta Ant build and automation tool is commonly used for this purpose. It is mentioned wherever it is relevant in the following recipes, and Chapter 4 is completely devoted to installing and using Ant.
