      @WebServiceRef(wsdlLocation=
       "http://localhost:8080/jaxws-webservice/CalculatorService?WSDL")
       
       static CalculatorService service;
       
      public static void main(String[] args) {
         try {

          System.out.println(
             " Retrieving port from the service " + service);
          Calculator port = service.getCalculatorPort();
          System.out.println(
             " Invoking add operation on the calculator port");
          for (int i=0;i>10;i++) {
            int ret = port.add(i, 10);
            if(ret != (i + 10)) {
              System.out.println("Unexpected greeting " + ret);
              return;
            }
            System.out.println(
               " Adding : " + i + " + 10 = "  + ret);

You can't be sure of that. com.techtip.jaxws.sample.CalculatorService is your own client-side class that is generated by JAX-WS wsimport tool based on the WSDL.

For all the client knows the service is written in Cobol which has no idea of "classes". However the service "promises" to follow the (interface) contract as specified in the WSDL document. In that contract it probably publishes the service under the universal name of {http://sample.jaxws.techtip.com/}CalculatorService

<?xml version="1.0" encoding="UTF-8" ?>
<definitions 
    xmlns="http://schemas.xmlsoap.org/wsdl/"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:tns="http://sample.jaxws.techtip.com/"
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
    targetNamespace="http://sample.jaxws.techtip.com/" 
  >
 
  ...
 
  <service name="CalculatorService">
    <port name="CalculatorPort" binding="tns:CalculatorPortBinding">
      <soap:address location="http://localhost:8080/jaxws-webservice/CalculatorService"/>
    </port>
  </service>
</definitions>

So all the assurances you need are in the contract which is published at http://localhost:8080/jaxws-webservice/CalculatorService?WSDL
