java.security.AccessControlException при отправке сообщения JMS в GAE

Question

Я пытаюсь отправить сообщение JMS дизайнеру tibco с использованием GAE. Вот мои коды:

try{ 
     Connection connection = null;   
     Session session = null; 
     MessageProducer msgProducer = null; 
     Destination destination = null; 
     String userName = null; 
     String password = null; 
     String destName = "q.message"; 

     TextMessage msg = null; 

     ConnectionFactory factory = new TibjmsConnectionFactory("localhost"); 

     connection = factory.createConnection(userName, password); 

     /* create the session */ 
     session = connection.createSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE); 

     /* create the destination */ 
     destination = session.createQueue(destName); 
     //replyDestination = session.createTopic("reply.topic"); 
     /* create the producer */ 
     msgProducer = session.createProducer(null); //changed for request-reply 
     //replyConsumer = session.createConsumer(replyDestination); //for request-reply 

     /* start the connection */ 
     connection.start(); 

     /* create text message */ 
     msg = session.createTextMessage(); 
     /* set message text */ 
     msg.setText(message); 
     //msg.setJMSReplyTo(replyDestination); //for request-reply 

     /* publish message */ 
     msgProducer.send(destination, msg); //Send XML message to destination 

     }catch(JMSException e){ 
      System.out.println("Error"); 
     } 

Однако после запуска этого веб-приложение, я получил следующее сообщение об ошибке:

Означает ли это, что GAE не может работать с JMS, как JMS использует соединение с базой данных и потребности GAE использовать собственную базу данных облаков? Как я могу обойти это?

Благодарим за помощь.

Попробуйте указать полный URL-адрес поставщика EMS в форме tcp: // host: port. Например:

ConnectionFactory factory = new TibjmsConnectionFactory("tcp://localhost:7222");
