Este é o meu código de servidor Java. Apenas recebendo mensagem do cliente e ecoando a mensagem de volta. Estou usando o WebSocket.
package pack.exp;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.server.ServerEndpoint;
@ServerEndpoint("/serverendpointdemo")
public class EchoServer
{
@OnOpen
public void handleOpen()
{
System.out.println("Client is now Connected...");
}
@OnMessage
public String handleMessage(String Message)
{
System.out.println("Message receive From Client... " + Message);
String replyMsg= "Echo from Server..." + Message;
System.out.println("Message sent to Client... " + Message);
return replyMsg;
}
@OnClose
public void handleClose()
{
System.out.println("Client is now Disconnected...");
}
@OnError
public void handleError(Throwable t)
{
t.printStackTrace();
}
}
The client is in Java Script, The client is sending the message and receiving the echo
from the server.

Eu estou usando o Glass Fish 4.0 e o Eclipse Juno. Mas quando eu estou executando iniciando o código no servidor, está demorando 7-8 minutos para iniciar o Glass Fish e depois disso também obtendo este erro
Unable to start server on time
java.util.concurrent.TimeoutException
