java.security.AccessControlException when sending JMS message in GAE - google-app-engine

Question

I am trying to send a JMS message to tibco designer using GAE. Here are my codes:
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");
}
However, after running this web application, i got the following error:

Does that mean that GAE cannot work with JMS as JMS uses database connection and GAE needs to use their own cloud database? How can I work around this?
Thank you for your help.

Try to specify the full EMS provider URL in the form tcp://host:port. For example:
ConnectionFactory factory = new TibjmsConnectionFactory("tcp://localhost:7222");
