Derivate from http://tomee.apache.org/examples-trunk/simple-webservice/README.html
The following is all that is required. No external xml files are needed. This class placed in a jar or war and deployed into a compliant Java EE server like TomEE is enough to have the Calculator class discovered and deployed and the webservice online.
import javax.ejb.Stateless;
import javax.jws.WebService;
@Stateless
@WebService(
portName = "CalculatorPort",
serviceName = "CalculatorService",
targetNamespace = "http://superbiz.org/wsdl",
endpointInterface = "org.superbiz.calculator.ws.CalculatorWs")
public class Calculator implements CalculatorWs {
@Inject
Operator delegate;
public int sum(int add1, int add2) {
return delegate.sum(add1,add2);
}
public int multiply(int mul1, int mul2) {
return delegate.multiply(mul1,mul2);
}
}
public class Operator {
public int sum(int add1, int add2) {
return add1 + add2;
}
public int multiply(int mul1, int mul2) {
return mul1 * mul2;
}
}
Having an endpoint interface is not required, but it can make testing and using the web service from other Java clients far easier.
import javax.jws.WebService;
@WebService(targetNamespace = "http://superbiz.org/wsdl")
public interface CalculatorWs {
public int sum(int add1, int add2);
public int multiply(int mul1, int mul2);
}
The wsdl for our service is autmatically created for us and available at http://127.0.0.1:4204/Calculator?wsdl. In TomEE or Tomcat this would be at http://127.0.0.1:8080/simple-webservice/Calculator?wsdl

In our testcase we see how to create a client for our Calculator service via the javax.xml.ws.Service class and leveraging our CalculatorWs endpoint interface.
With this we can get an implementation of the interfacce generated dynamically for us that can be used to send compliant SOAP messages to our service.
