Join Alex Theedom for an in-depth discussion in this video ✓ Solution: Code programmatic endpoint, part of WebSocket Programming with Java EE.
- [Instructor] So how do you get on?…Well here's my solution.…Let's start with the application configuration class.…Now, firstly you must implement the interface…server application config.…And in the method, get endpoint configs…I have created two lists,…one for the encoder class and one for the decoder class,…which I then add to the construction of the endpoint.…Now this is where I create the endpoint…and associate the class that handles…the WebSocket lifecycle and the URI.…So now let's take a look at the chat server endpoint class.…The first thing you need to do…is to extend the endpoint class…and then implement the only abstract method on open.…
Let's go down and have a look at the method on open.…In the on open method is where the magic happens.…First I add the message handler to the session object.…For simplicity, I have only added logic…that prints the message out to a log file.…Then I obtain the ring directly from the session…by calling the get path parameter method.…And then I added to the user defined…
Join Alex Theedom as he guides you through the lifecycle of a WebSocket connection, and discusses the Java EE WebSocket programming methodologies: annotation and programmatic. He shows how to secure and encrypt WebSocket endpoints and use simple techniques to test their implementation. In addition, he explains how to integrate the JSON-processing API and build a front-end and server based WebSocket client.
