JMS Sending to a Queue

Question

Hi there:
I'm trying to send messages from a Servlet to a queue asynchronously. I've been reading a lot but I still don't have a clear idea about if this is possible or not.
I've created a Connection Factory with One-way message sending enabled for both topics and queues, and I use this code on the sender.
code:
Context ctx = new InitialContext();
qconFactory = (QueueConnectionFactory) ctx.lookup(JMS_FACTORY);
qcon = qconFactory.createQueueConnection();
queue = (Queue) ctx.lookup(QUEUE);
qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
qsender = qsession.createSender(queue);
qcon.start();qsender.send(msg,DeliveryMode.NON_PERSISTENT,4,1000);
qsender.close();qsession.close();qcon.close();
This code works nice but I need to know how to make this sendings asynchronously if it is possible, I don't want to wait to the queues acknowledge.
Is the "QueueSender.send(...)" method valid only for synchronous messaging?
Thanks!

Sorry I didn't address the answers more clearly. You were correct on the answers except with:
          Switch from using a resource-reference to a direct reference for a send? Answer: No. We are only trying a direct send, not utilizing the resource-reference.
          We are already using "false" for the connection.create[Queue]Session code.
          Should we be trying something else because of transactional behavior of not utilizing the resource-reference for the send as you thought?
          We have tried the queue as XA and non-XA and neither work.
