Once configuration is complete, you can inject a JMS TopicPublisher and TopicSession into any component: 
@Name("stockPriceChangeNotifier")
public class StockPriceChangeNotifier {
  @In private TopicPublisher stockTickerPublisher;   

  @In private TopicSession topicSession;

  public void publish(StockPrice price) {
    try {
      stockTickerPublisher.publish(topicSession
                                   .createObjectMessage(price));
    } catch (Exception ex) {
      throw new RuntimeException(ex);
    } 
  }
}
Or, to work with a queue: 
@Name("paymentDispatcher")
public class PaymentDispatcher {
  @In private QueueSender paymentQueueSender;   
    
  @In private QueueSession queueSession;
    
  public void publish(Payment payment) {
    try {
      paymentQueueSender.send(queueSession.createObjectMessage(payment));
    } catch (Exception ex) {
      throw new RuntimeException(ex);
    } 
  }
}
