I hate asking such a vague question, but I'm having a hard time finding a simple example. Here's what I have so far:
public class JettyWebSocketServlet extends WebSocketServlet{
@Override
public void configure(WebSocketServletFactory factory) {
factory.register(MyEchoSocket.class);
}
}
@WebSocket
public class MyEchoSocket {
@OnWebSocketMessage
public void onText(WebSocketConnection conn, String message) {
System.out.println("text: " + message);
try {
conn.write(null, new FutureCallback(), "got: " + message);
} catch (Exception e) {
e.printStackTrace();
}
}
}
The embedded Jetty examples I can find always show something like the following, to start a Server instance running, but I don't know how to instantiate my WebSocketServlet.
Server server = new Server(8080);
server.start();
server.join();
How do I create an embedded server that can handle WebSocket connection requests?
Here is servlet approach:
1) In this case, don't need to use this code (it is container responsibility):
2) Create web.xml descriptor for servlet:
Now, when you write JS:
message is handled with onText method of your MyEchoSocket
Here is tutorial for more understanding servlets, tutorial
Good luck.

Original Answer
There's an example found in the test cases.

Short Answer:
This will create a simple server that handles 1 context, the root context.
If you want to bind the WebSocketHandler to another context, wrap it in a ContextHandler.
This will bind your websocket to
