Hi,
I am trying to invoke my first Web Service but kept getting the same error msg: "failed attempting to read SOAP response from service. This is probably due to a communication error"

Code:
 
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="HelloService"
    targetNamespace="http://dl.dropbox.com/u/2920864/HelloService.wsdl"
