Write jax-ws web service and generate WSDL without XSD

I wrote a simple JAX-WS web service for tomcat application server on java.

I have one interface and on implementation class:
interface

@WebService(name = "myWs")
@SOAPBinding(style = Style.RPC)
public interface IMyWs {
    @WebMethod(operationName = "getUser")
    Response getUser(@WebParam(name = "phone", mode = Mode.IN) String phone);

}

implementation

@WebService(endpointInterface = "ge.mari.IMyWs")
public class MyWs implements IMyWs {
    @Override
    public Response getUser(String phone) {
               // SOME CODE
        return response;
    }
}

My problem is that, in my wsdl file Response class is defined in xsd file.
This is the snippet from my wsdl file

<types>
<xsd:schema>
          <xsd:import namespace="http://ws.mari.ge/" schemaLocation="http://localhost:8080/MyServcie/MyWs?xsd=1">
</xsd:import>
</xsd:schema>
</types>

How can I make web service to generate all types in WSDL file instead of separate XSD file?
Should I change any configuration or add some annotation to my web service?
