Server WebSocket Clients, with Jetty
Previously I discussed how to write a Server which uses a persistent WebSocket Client, using the Netty framework to make things go. Netty is configured through establishing a Channel Pipeline, which is great if you need a very flexible system for handling network input and output. For most projects however, this sort of power can be overkill.
Jetty, among other great things, contains a WebSocketClient implementation. Getting this up and running is very simple: you?ll need a WebSocketClientFactory, where you can configure various settings, and a WebSocketClient which also has a bunch of settings to flip around to meet your needs. Once you have those, you?ll need a class that implements WebSocket.OnTextMessage ?and you?re pretty much done at this point.
The code for sending and receiving messages becomes equally simple:
