У меня есть JMS-приложение (использующее стеклянную рыбку), которое отлично работает на localhost.После развертывания на моем сервере я продолжаю получать приведенную ниже трассировку стека при ПЕРВОМ ВЫЗОВЕ в службу.

Я уверен, что закрываю все ресурсы, но даже если это не так, как я могу запуститьиз пулов соединений прямо при первом вызове?
Ниже приведен код в коде ReadOfflineMessage.java.
try {
QueueConnectionFactory queueConnectionFactory = (QueueConnectionFactory) context.lookup("jms/MyConnectionFactor");
queueConnection = queueConnectionFactory.createQueueConnection();
QueueSession queueSession = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = (Queue) context.lookup("jms/CloxQueue");
QueueReceiver queueReceiver = queueSession.createReceiver(queue, "client_name = '" + clientName + "'");
queueReceiver.setMessageListener(new MessageListener() {
@Override
public void onMessage(Message message) {
if (message instanceof TextMessage) {
try {
String clientMessage = ((TextMessage) message).getText();
System.out.println("Message: " + clientMessage);
clientMessage = clientMessage.replace("message:", "");
com.trinisoft.cloxserver.models.Message parsedMessage = parseMessage(clientMessage);
System.out.println("parsed Message: " + message);
Client toClient = ClientList.getClient(parsedMessage.getTo());
toClient.getClientWriter().append("message:" + clientMessage + "\n");
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
queueConnection.start();
} catch (Exception e) {
e.printStackTrace();
}
Из строки трассировки стека 67 есть
queueConnection = queueConnectionFactory.createQueueConnection();
Спасибо.
