Calling external web service

I am new to Mule. I am trying to call http://www.webservicex.net/globalweather.asmx/GetCitiesByCountry?method=GetCitiesByCountry. I want Mule to read cityrequest.xml, create a request using WSDL and send it to the web service. This is my configuration file, request is being sent to the web service but response is empty. Please help.
