Can I create a new Queue/Topic in client application?

Question

In sun's JMS turorial the application client sends messages to the queue, which is created administratively, using the j2eeadmin command. Can I create a new destination(queue or topic) in my client's code?
Thanks very much.

Thank you very much, flhood. This is my first time to gain aid from website except my school's BBS.
But I still cann't solve the problem, here is my code, can you help me to check it if there is anywhere that I might do wrong?( I omit the try/catch part)
QueueConnectionFactory queueConnectionFactory =null;
QueueConnection queueConnection =null;
QueueSession queueSession =null;
Queue queue =null;
Queue tempQueue =null;
QueueSender queueSender =null;
TextMessage message =null;
final int NUM_MSGS;
Context jndiContext =null;
jndiContext =new InitialContext();
queueConnectionFactory =(QueueConnectionFactory)jndiContext.lookup("QueueConnectionFactory");
queueConnection =queueConnectionFactory.createQueueConnection();
queueSession =queueConnection.createQueueSession(false,Session.AUTO_ACKNOWLEDGE);
queueConnection.start();
queue =queueSession.createQueue("MyQueue");
tempQueue =queueSession.createTemporaryQueue();(Actually I don't know why I shall need a tempQueue if I have the queue.)
queueSender =queueSession.createSender(queue);
message =queueSession.createTextMessage();
NUM_MSGS=10;
for (int i =0;i <NUM_MSGS;i++){
message.setText("This is message "+(i +1));
System.out.println("Sending message:"+message.getText());
queueSender.send(message);
These codes run well if I lookup in the JNDI for the existing queue "MyQueue", but when I try to make it dynamically, the resutlt shows(I only use texteditor+j2sdk1.4+j2ee1.3.1):
Java(TM) Message Service 1.0.2 Reference Implementation (build b14)
Sending message:This is message 1
Exception occurred:javax.jms.InvalidDestinationException: No Destination found f
or name: MyQueue
I use deloytool to check the destionation, of course the "MyQueue" hasn't been created, but I use try/catch to brace these two line:
queue =queueSession.createQueue("MyQueue");
queueSender =queueSession.createSender(queue);
Nothing gain.
They are really puzzling me!
