This implementation overrides the superclass method to use JMS 1.0.2 API.

{
		if (isPubSubDomain()) {
			return ((TopicConnection) con).createTopicSession(isSessionTransacted(), getSessionAcknowledgeMode());

 protected Connection getConnection(JmsResourceHolder holder) 
{
		return holder.getConnection(isPubSubDomain() ? (Class) TopicConnection.class : QueueConnection.class);
}

This implementation overrides the superclass method to accept either a QueueConnection or a TopicConnection, depending on the domain.

 protected Session getSession(JmsResourceHolder holder) 
{
		return holder.getSession(isPubSubDomain() ? (Class) TopicSession.class : QueueSession.class);
}

This implementation overrides the superclass method to accept either a QueueSession or a TopicSession, depending on the domain.

 protected boolean isClientAcknowledge(Session session) throws JMSException 
{
		return (getSessionAcknowledgeMode() == Session.CLIENT_ACKNOWLEDGE);
}

This implementation overrides the superclass method to avoid using JMS 1.1's Session getAcknowledgeMode() method. The best we can do here is to check the setting on the listener container.
