Programmatically, by extending the endpoint class and overriding its lifecycle methods. And by decorating in class with the appropriate annotations. The programmatic method represents an endpoint by instances of the endpoint class. The OnOpen method is overwritten and message handling logic is written. Two other lifecycle methods can be overwritten, onError and OnClose. And all the endpoints are registered and URI is defined in an application configuration class. And messages are sent by calling a send method on the client session. The annotation methodology is arguably much simpler, as all WebSocket configuration happens in the same class and is done by passing metadata to the appropriate annotation. So you annotate a class ServerEndpoint and specify the endpoint's URI. Optionally, you can specify a…
