I want to get the WSDL file for a webservice and the only thing I have is its URL (like webservice.example/foo).
If I use the URL directly only an error response is delivered.
By postfixing the URL with ?WSDL
If the URL is for example:
http://webservice.example:1234/foo
You use:
http://webservice.example:1234/foo?WSDL
And the wsdl will be delivered.
