Отключение веб-сокета в OpenShift (с WildFly 8.2.1)
Я использую OpenShift и WildFly 8.2.1 final для реализации нового веб-сокета HTML5. я использовалэтот учебник, чтобы настроить этот проект.
Всякий раз, когда я открываю свой MyTest.html, вот что регистрирует JavaScript:
JS: Server Connected...
JS: Server Disconnected...
Сервер подключается, а затем немедленно отключается. Зачем? Что я делаю неправильно? Есть что-то, чего мне не хватает?
Вот код режима ->
serverendpoint.java
package testing;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.server.ServerEndpoint;
@ServerEndpoint("/serverendpoint")
public class serverendpoint {
@OnOpen
public void handleOpen () {
System.out.println("JAVA: Client is now connected...");
}
@OnMessage
public String handleMessage (String message) {
System.out.println("JAVA: Received from client: "+ message);
String replyMessage = "echo "+ message;
System.out.println("JAVA: Send to client: "+ replyMessage);
return replyMessage;
}
@OnClose
public void handleClose() {
System.out.println("JAVA: Client is now disconnected...");
}
@OnError
public void handleError (Throwable t) {
t.printStackTrace();
}
}
MyTest.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>My WS Website</title>
</head>
<body>
<form>
<input id="textMessage" type="text">
<input onclick="sendMessage();" value="Send Message" type="button">
</form>
<br>
<textarea id="messageTextArea" rows="10" cols="50"></textarea>
<script type="text/javascript">
var wsUri = "ws://" + document.location.hostname + ":8000" + document.location.pathname + "serverendpoint";
var webSocket = new WebSocket(wsUri);
var messageTextArea = document.getElementById("messageTextArea");
webSocket.onopen = function(message) { processOpen(message);};
webSocket.onmessage = function(message) { processMessage(message);};
webSocket.onclose = function(message) { processClose(message);};
webSocket.onerror = function(message) { processError(message);};
function processOpen (message) {
messageTextArea.value += "JS: Server Connected..."+"\n";
}
function processMessage(message) {
messageTextArea.value += "JS: Receive from Server ==> "+message.data+"\n";
}
function sendMessage () {
if (textMessage.value !="close") {
webSocket.send(textMessage.value);
messageTextArea.value += "JS: Send to Server ==> "+textMessage.value+"\n";
textMessage.value="";
} else webSocket.close();
}
function processClose(message) {
webSocket.send("JS: Client disconnected...")
messageTextArea.value += "JS: Server Disconnected..."+"\n";
}
function processError (message) {
messageTextArea.value += "JS: error ..."+"\n";
}
</script>
</body>
