WsContextListener (Apache Tomcat 10.0.27 API Documentation)

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

All Implemented Interfaces:

ServletContextListener, java.util.EventListener
```
public class WsContextListener
extends java.lang.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.
