Once a username and password challenge has been implemented the next step is to configure encryption of the web communication itself. This will ensure that no one can snoop on your private conversations. You cantake a light look at how to enable HTTPS encryption for the chat application.
- [Instructor] Now let's see how to encrypt…our WebSocket connection so that…no one can snoop on our conversations.…We need to make some configurations…to the deployment descriptor,…and change the URI endpoint in the JavaScript file…that creates the client connection…in the client application.…I have opened here already the web.xml file,…and in this file, we simply need to specify…the transport guarantee as confidential.…So, let's do that first.…So, here in this location,…we simply need to start specifying…how to use the data constraints,…and then we're gonna use the data constraint…to specify it as confidential.…
And that's it.…We now have an encrypted access…to the rooms slash star URI.…Now that the chat endpoint is encrypted,…the protocol schema has changed from WS to WSS,…and the port has changed to 8181,…so you must change the service location URI…in the WebSocket client JavaScript file…in the webapp directories.…So I have this open here already,…and this is the URL we need to change.…We just simply change the protocol to WSS,…

6/13/2017Join 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.
