title: Difference between Mule Connectors and Transports
body: <p>I'm trying to evaluate the set of out-of-the-box transports provided by Mule, and compare it with the offerings from e.g. ServiceMix and OpenESB.</p>
  
  <p>On Mule's homepage, I find a list of supported transports at:</p>
  
  <p><a href="http://www.mulesoft.org/documentation/display/current/Transports+Reference" rel="nofollow">http://www.mulesoft.org/documentation/display/current/Transports+Reference</a></p>
  
  <p>However i also find a list of Connectors at:</p>
  
  <p><a href="http://www.mulesoft.org/connectors" rel="nofollow">http://www.mulesoft.org/connectors</a></p>
  
  <p>There seem to be at least some overlap between these lists, but some technologies are listed as transports, and not as connectors, for example there is a Quartz transport, but not a connector.</p>
  
  <p>So the question is: What exactly is the difference between a Mule Transport and a Mule Connector, and why is e.g. Quartz a transport and not a connector?</p>
