Tomcat websocket closes connection

I run simple websocket server on Tomcat:

package server.ws;

import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.server.ServerEndpoint;




@ServerEndpoint("/websocketendpoint")

public class WsServer {

    @OnOpen
    public void onOpen(){
        System.out.println("Open Connection ...");
    }

    @OnClose
    public void onClose(){
        System.out.println("Close Connection ...");
    }

    @OnMessage
    public String onMessage(String message){
        System.out.println("Message from the client: " + message);
        String echoMsg = "Echo from the server : " + message;
        return echoMsg;
    }

    @OnError
    public void onError(Throwable e){
        e.printStackTrace();
    }

}

Client that connects to my server complains regarding Tomcat closes session after echo was transmitted. How to make the server to not close the connection after echo?

i'm not sure, but i guess onMessagehas no return value. for me, the following code works fine and i have any problems

@OnMessage
public void message(final String message, final javax.websocket.Session session) throws IOException {
    for (final Session s : session.getOpenSessions()) {
        final Basic endpoint = s.getBasicRemote();
        endpoint.sendText(message);
    }
}
