SOAP server reads web method parameters as null

Question

I have a client that connects to a SOAP server endpoint:

Endpoint.publish("http://localhost:8081/todo", new ToDoWebService());

The server offers the next simple method:

@WebService
public class ToDoWebService {

    @WebMethod()
    public String addToDo(String task, String context, String project, int priority) {
        return "ToDo: 
 "
                + "	 Task    :  "+task+"
"
                + "	 Context :  "+context+"
"
                + "	 Project :  "+project+"
"
                + "	 Priority:  "+priority;
    }
}

This is the client:

public class Client {

    public static void main(String[] args) {
        ToDoWebServiceService tdwss = new ToDoWebServiceService();
        ToDoWebService tdws = tdwss.getToDoWebServicePort();

        System.out.println(tdws.addToDo("Task 1","My Context","My Project",9));
    }
}

The thing is that the connection between client and server is succesful, but not entirely: the pass of the arguments from the client to the service is not made as expected, been this the result on the client once executed:

enter image description here

The server doesn't receive correctly the arguments that the client has passed with the method "addToDo()" call. It returns the string format expected but with nulls instead the arguments passed by the client. And that's what I can't figure out...

Of course, I'm pretty confident the WSDL file is well written:

As well as the schema "toDo.xsd":

I've tried different actions in the server method, as writing the string with the parameter in a file, but the result is the same, an error cause the parameters are null. That's what I think proves that the failure is located in the way the server receive the parameters passed to the "addToDo()" method.

I've review the WSDL & schema files over and over....but I've not been able to find what make this code run wrongly. I've also tested this code with the SoapUI software and the outcome is the same. ¿Any ideas?

P.D.: Sorry about all the posted code.

I reviewed your WSDL and XSD in your project todows-cli-ws and the problem is the WSDL and XSD files in your client project are outdated!

For example, this is the current content of the XSD file of your server.

Note that the current name of the params are arg0, arg1, arg2 and arg3. The server expects as param names task, context, project and priority, and therefore the method is invoked with the default values (null for a String and 0 for an int).
