I am new Salesforce. I've a requirement you call an external Java Web service from apex using SOAP. JAVA developers has provided their Wsdl which is supposed to be used in Salesforce to generate apex class for Java Web service.
Here I've a doubt that here do we need to write another apex class to call the newly generated apex class ( from Wsdl) which in turn connects to external service. Can anybodypls help how to get through it?
