我正在开发一个简单的应用程序，帮助我学习Java中WebSocket和Tyrus概念。这是我的服务器端（服务器终端）和pom.xml以及客户端和pom.xml：
服务器端
@ServerEndpoint(value="/websocket/{client-id}")
public class MyServerEndpoint {
private static final LinkedList<Session> clients = new LinkedList<Session>();
@OnOpen
public void onOpen(Session session) {
clients.add(session);
}
@OnMessage
public void onMessage(String message,@PathParam("client-id") String clientId) {
for (Session client : clients) {
try {
client.getBasicRemote().sendObject(clientId+": "+message);
} catch (IOException e) {
e.printStackTrace();
} catch (EncodeException e) {
e.printStackTrace();
}
}
}
@OnClose
public void onClose(Session peer) {
clients.remove(peer);
}
}

客户端
MyClient.java
@ClientEndpoint
public class MyClient {
@OnOpen
public void onOpen(Session session) {
System.out.println("Connected to endpoint: " + session.getBasicRemote());
try {
session.getBasicRemote().sendText("Hello");
} catch (IOException ex) {
}
}
@OnMessage
public void onMessage(String message) {
System.out.println(message);
}
@OnError
public void onError(Throwable t) {
t.printStackTrace();
}
}
App.java
public class App {
public Session session;
protected void start()
{
WebSocketContainer container = ContainerProvider.getWebSocketContainer();
String uri = "ws://localhost:8080/TyrusJacpFXClient/websocket/desktop-client";
System.out.println("Connecting to " + uri);
try {
session = container.connectToServer(MyClient.class, URI.create(uri));
} catch (DeploymentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String args[]){
App client = new App();
client.start();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String input = "";
try {
do{
input = br.readLine();
if(!input.equals("exit"))
client.session.getBasicRemote().sendText(input);
}while(!input.equals("exit"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

我遇到了这个错误：
Exception in thread "main" java.lang.RuntimeException: Could not find an implementation class.
at javax.websocket.ContainerProvider.getWebSocketContainer(ContainerProvider.java:73)
at org.hwc.App.start(App.java:25)
at org.hwc.App.main(App.java:40)
有人能帮我看看问题吗？服务器在GlassFish 4.0中运行。
