Jetty also provides a Jetty WebSocket Client Library to write make talking to WebSocket servers easier.
To use the Jetty WebSocket Client on your own Java project you will need the following maven artifacts.
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>websocket-client</artifactId>
  <version>${project.version}</version>
</dependency>To use the WebSocketClient you will need to hook up a WebSocket object instance to a specific destination WebSocket URI.

            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        }
    }
}The above example connects to a remote WebSocket server and hands off a SimpleEchoSocket to perform the logic on the websocket once connected, waiting for the socket to register that it has closed.

    {
        System.out.printf("Got msg: %s%n",msg);
    }
}When the SimpleEchoSocket connects, it sends 2 Text messages and then closes the socket.
The onMessage(String msg) receives the responses from the remote server WebSocket and outputs them to the console.
