title: How to identify whether a web service is asynchronous or synchronous
body: <p>I know that there are two types of web services called asynchronous web services and synchronous web services. What I want to know are</p>
  
  <p>1.
   Can I identify whether a web service is asynchronous or synchronous by inspecting the WSDL of the service? Or is there any other way such as inspecting the generated stub etc?</p>
  
  <p>2.
  Can I develop an asynchronous client for a synchronous web service? Does it make sense?</p>
  
  <p>Thank you.</p>
