title: Batch consuming of JMS messages
body: <p>The <code>MessageListener</code> interface only defines a method <code>onMessage</code> that receives a single <code>Message</code> as argument. I'm looking for a way to get multiple <code>Message</code>s from a queue so that I can process the batch and then acknowledge all the <code>Message</code>s in the batch.</p>
  
  <p>Is there such feature in JMS world? If no, is it supported by ActiveMQ as an extension?</p>
  
  <p>Thanks, Mickael</p>
