Package org.apache.tomcat.websocket.server

# Class WsContextListener

java.lang.Object
org.apache.tomcat.websocket.server.WsContextListener

All Implemented Interfaces:
  `EventListener`, `ServletContextListener`

public class WsContextListener extends Object implements ServletContextListener
In normal usage, this `ServletContextListener` does not need to be explicitly configured as the `WsSci` performs all the necessary bootstrap and installs this listener in the `ServletContext`. If the `WsSci` is disabled, this listener must be added manually to every `ServletContext` that uses WebSocket to bootstrap the `WsServerContainer` correctly.
