Calling a Web Service Using Java Proxy

Hi Experts,

I am working on a scenario where in I need to send two numbers to a Web service and obtain response from the same.Now the problem is that I cant have the wsdl of the Webservice hence cannot use the SOAP adapter on the reciever side. So I am planning to use Server Java proxy. Please help me with how exactly a webservice can be called in using Java proxy and how a response can be obtained from the same

Many Thanks,

Neha
