Using JmsTemplate

public int getMessageCount(String messageSelector)
{
    return jmsTemplate.browseSelected(messageSelector, new BrowserCallback<Integer>() {
        @Override
        public Integer doInJms(Session s, QueueBrowser qb) throws JMSException
        {
            return Collections.list(qb.getEnumeration()).size();
        }
    });
}
