Defaults . Text fields are populated with the values we got from the JSON-formatted

In this chapter, we covered how to develop Java EE applications using the new
WebSocket protocol. First, we examined a sample application using WebSocket
provided by NetBeans, examining its source code to better understand how to
write our own applications. We then applied that knowledge to develop our own
WebSocket application via the new Java API for WebSocket introduced in Java EE 7,
taking full advantage of NetBeans wizards to aid us in the creation of our application.
