4.4. Top-Level Elements

The TLD server.xml file contains the <Server> top-element, which contains the <Service> elements. Any other elements are nested in these two elements.

4.4.1. Server

The Server is a container element that represents the entire servlet container and is the only parent of any other element, that is, it is the only top-level element.
It can contain multiple Service, GlobalNamingResources and Listener elements.


The Server element in the JBoss Web's server.xml file contains multiple Listener elements. Amongst others, the org.apache.catalina.core.AprLifecycleListener and the org.apache.catalina.core.JasperListener. If the mod_ cluster load balancer is enabled for the profile, also the org.jboss.web.tomcat.service.deployers.MicrocontainerIntegrationLifecycleListener is required.
The AprLifecycleListener and the JasperListener are used to start up and shut down APR and initialize Jasper. Removing the Listener elements is therefore discouraged just as removing the MicrocontainerIntegrationLifecycleListener.
