import org.apache.axis.client.Service;

import org.apache.axis.client.Call;

import javax.xml.namespace.QName;

public class Client {

public static void main(String[] args) {

try {

String endpoint = "http://localhost:8080/DestinedProjectname/AddFunction.jws?sdlwsdl";

Service service = new Service();

Call call = (Call) service.createCall();

call.setOperationName(new QName(endpoint, "addtwonumbers"));

call.setTargetEndpointAddress(new java.net.URL(endpoint));

System.out.println("In the Try"+call);

Integer ret = (Integer) call.invoke(new Object[] {

new Integer(10), new Integer(11) });

System.out.println("addInt(5, 7) = " + ret);

} catch (Exception e) {

System.err.println("Execution failed. Exception: " + e);

e.printStackTrace(); }

}

}

3) Create Destined project to be webserviced
public class AddFunction {
public int addInt(int a, int b){
return (a+b);
}}

4)Copy the AddFunction Class and Rename with (.jws) extention
