My code was earlier working with soapUi2.5. but when I started working with soapUI2.5.1, I started getting this error. com.eviware.soapui.impl.wsdl.mock.DispatchException: Missing operation for soapAction [http://SEWSI.ServiceContracts/2008/09/ReceiveSubscription%5D and body element [{h ttp://SEWSI.ServiceContracts/2008/09}ReceiveSubscriptionRequest] with SOAP Version [SOAP 1.1] I would appreciate if some can explain me what this signifies.
