title: JMS and ESB - how they are related?
body: <p>For me JMS and ESB seem to be very related things and I'm trying to understand how exactly they are related.</p>
  
  <p>I've seen a sentence that JMS can be used as a transport for ESB - then what else except the transport should be present in such an ESB? Is JMS a simple ESB or if not, then what it lacks from the real ESB?</p>
