Obs: the websocket server is the api-jersey

Today's top browsers already support websocket, with very simple code:

	var websocket = new WebSocket("ws://localhost:8080/api-jersey/chat");

• To open connection

websocket.onopen = function() {
	log("Conected !!!");
};

• To close connection

websocket.onclose = function() {
	alert("desconnected");
};

• To error

websocket.onerror = function() {
	log("an error has occurred");
};

• To receive messages

websocket.onmessage = function(data) {                
	var message = "<p>" + data.data + "</p>";
	var messageArea = document.getElementById("messageArea");
	messageArea.innerHTML += message;
	messageArea.scrollTop = messageArea.scrollHeight;
};

• to send message

function sendMessage(msg) {
	log("Enviar mensagem (" + msg + ")");
	websocket.send(msg);
}
