Java EE (Java Enterprise Edition) General Discussion

I have been working on a Web Service the last 2 weeks and finally got a connection working with JAVA and AXIS. The question I have is this. First off, my code listed below is so very simple and it works. Now all the so called examples that I have seen out there seem to have the code replicated from the SoapBindingStub file and if I try to duplicate the way that they have there code, I can not get it to work.

At the end of this file is a sample of what I have seen others posting. So what all should be in my client to communicate with the stubs of the Service?

Why would the others be so redundant by putting code from the soapbindingstub into a client?


/////////////////////////////////////////////////////////////////////////////////////////
Assuming you already have a web service deployed.
You have gotten a wsdl.
You have ran WSDL2Java on the wsdl

Your client would look like the following.
/////////////////////////////////////////////////////////////////////////////////////////

import folderPathToWSDL2JavaGeneratedFolder.*;

public class MyClientCallerToWebServiceX {

   public static void main(String[] args) throws Exception {
               // create an instance of our service locator
         MyWebServicesServiceLocator locator = new MyWebServicesServiceLocator();

               // create an instance or our SoapBindingStub
         MyWebServicesSoapBindingStub stub = (MyWebServicesSoapBindingStub) locator.getMyWebServices();

               // make a call to a method we created in our web service
       System.out.println("Data on server: " + (stub.getSomeMethodOfMine("pass in a value").toString()));
 }
}
