This section focuses on setting production environments and realistic test environments, including post-installation and customization tasks for administrators; setting up Web servers and application servers; and administering the application servering environment.
An application server is a Java™ Virtual Machine (JVM) that runs user applications. The application server collaborates with the Web server to return a dynamic, customized response to a client request. The client request can consist of servlets, JavaServer Pages (JSP) files, and enterprise beans, and their supporting classes.
