I have this websocket client, that connects to the server.

@ClientEndpoint
class WSClient 
 private static Object waitLock = new Object();

 @OnMessage
 public void onMessage(String message) throws IOException 
 System.out.println("Received msg: " + message);
 

 private static void wait4TerminateSignal() 
 synchronized (waitLock) 
 try 
 waitLock.wait();
 catch (InterruptedException e) 
 
 
 

 public static void main(String[] args) 
 WebSocketContainer container = null; //
 Session session = null;
 try 
 //Tyrus is plugged via ServiceLoader API. See notes above
 container = ContainerProvider.getWebSocketContainer();
 //WS1 is the context-root of my web.app
 //ratesrv is the path given in the ServerEndPoint annotation on server implementation
 session = container.connectToServer(WSClient.class, URI.create("ws://localhost:8080/websocket"));
 // message of bytes
 session.getAsyncRemote().sendBinary(ByteBuffer.wrap(bytes));
 wait4TerminateSignal();
 catch (Exception e) 
 e.printStackTrace();
 finally 
 if (session != null) 
 try 
 session.close();
 catch (Exception e) 
 e.printStackTrace();
 
 
 
 

Then, it sends a message that the server accepts and continues with the process. However the server sends back the response which should be handled by @OnMessage annotated method, however there is no response. Server code uses Spring and works properly - it sends messages to other clients as it should.

Thanks for help!
