public class WebAppContext
extends ServletContextHandler
implements WebAppClassLoader.Context

Web Application Context Handler. The WebAppContext handler is an extension of ContextHandler that coordinates the construction and configuration of nested handlers: ConstraintSecurityHandler, SessionHandler and ServletHandler. The handlers are configured by pluggable configuration classes, with the default being WebXmlConfiguration and JettyWebXmlConfiguration.
