-The firsst three
+An exceptions that are thrown by displayMessage or playWithMessage are sent to the exceptionHandler method.
+Once all other operations/actions are complete the last line is tied to "noOperation" which simply returns
+the same message that it is sent with a call to the okMethod, in this case, sendResponse.  This is because
+sendResponse doesn't intend to return the Message.
 
+An alternative approach could be:
+   	   <action class="quickstart.MyJMSListenerAction" process="sendResponse" exceptionMethod="exceptionHandler"/>
+	public Message sendResponse(Message message) {
+	   try {
+		   logHeader();
+		   System.out.println(new String(message.getBody().getContents()));
+		   logFooter();
+		   ReturnJMSMessage.sendMessage(message,"quickstart_helloworld_action_Response");
+	   } catch (Exception e) {
+		   logHeader();
+		   System.out.println(e.getMessage());
+		   logFooter();
+	   }
+	   return message; // return exactly what was passed in.
+  	 }
+An ESB action class must have a constructor that accepts a ConfigTree argument like the following:
+ public MyJMSListenerAction(ConfigTree config) { _config = config; } 
+ 
+A ConfigTree is an object holding any attributes associated with the action declaration in the esb-config.xml
