JAX-WS Web Service with XFire Client

Question

I wrote a simple web service and client using XFire. However the server now needs to be JAX-WS. I wrote a simple service using NetBeans but I can't seem to get it to work with XFire. JAX-WS doesn't seem to like the SOAP XFire is sending it and the parameters passed into the web method are nulls instead of the intended values.
Here is my web service:
package org.me.hi;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;
import javax.jws.soap.SOAPBinding.ParameterStyle;
@WebService(name="HelloWS", targetNamespace="http://hi.me.org")
@SOAPBinding(style=Style.DOCUMENT, use=Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED)
public class HelloWS {
    @WebMethod(operationName="add", action="")
    @WebResult(name="return", targetNamespace="http://hi.me.org")
    public Integer add(Integer a, Integer b) {
        if (a == null)
            System.out.println("a is null");
            return null;
        if (b == null)
            System.out.println("b is null");
            return null;
        System.out.println("a: " + a + " b: " + b);
        return a + b;
}Here is the WSDL:
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns:tns="http://hi.me.org" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://hi.me.org" name="HelloWSService">

      <xsd:import namespace="http://hi.me.org" schemaLocation="http://localhost:8084/HelloWS/HelloWS?xsd=1"/>
    </xsd:schema>

  </message>

    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="add">
      <soap:operation soapAction=""/>
      <input>
        <soap:body use="literal"/>
      </input>
      <output>
        <soap:body use="literal"/>
      </output>
    </operation>
  </binding>
  <service name="HelloWSService">
    <port binding="tns:HelloWSPortBinding" name="HelloWSPort">
      <soap:address location="http://localhost:8084/HelloWS/HelloWS"/>
    </port>
  </service>
</definitions>Here is my quick and dirty XFire client:
package org.me.hi;
import java.net.MalformedURLException;
import java.net.URL;
import org.codehaus.xfire.client.Client;
public class HelloTest {
    public static void main(String[] args) {
        Client client;
        try {
            client = new Client(new URL("http://localhost:8085/HelloWS/HelloWS?wsdl"));
            Object[] results = client.invoke("add", new Object[] {1, 2});
            if (results.length != 0) {
                System.out.println("result: " + (Integer)results[0]);
            } else {
                System.out.println("null return");
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
}Here is the SOAP I intercepted between the XFire client and the JAX-WS service:
Calling the web method:

    <ns1:addResponse></ns1:addResponse>
  </soapenv:Body>
</soapenv:Envelope>Console at the server side:
a is nullConsole at the client side:
null returnNot sure what I'm doing wrong, but I wrote a quick JAX-WS client using NetBeans and it works. We would like to keep using XFire if possible. Here is the SOAP between the JAX-WS client and the JAX-WS web service.
