I have created classes from WSDL2APEX, see my previous question for example: Test on WSDL2APEX classes.
But this is a different bunch of classes. The webservice in the example works well. I have read all the debug log, the only thing that is related to the error is:
System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: An unknown error has occurred. faultcode=s:Client faultactor=
Here I would like to ask, how do I locate what error is happening? Is there a way for me to get the details of the error?
Thanks a lot.
