我正在尝试使用 GAE 向 tibco 设计师发送 JMS 消息。这是我的代码：
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");
}
但是，运行此 Web 应用程序后，我收到以下错误：

这是否意味着 GAE 不能与 JMS 一起使用，因为 JMS 使用数据库连接，而 GAE 需要使用自己的云数据库？我该如何解决这个问题？
谢谢您的帮助。
