Hi,

I found what the problem is!!

You are using a multiple portType for WSDL and it is not supported. Because, portType shows for getting in/out messages at a single port.

Anyways, I deleted other all the portypes and kept only one portType name="CurrencyConvertorSoap", and i completed parsing the wsdl without any errors and it has generated a class as well.

Am attaching the generated class as well as WSDL file i used to generate the class. Please find it as shown below.
