How to generate two clients from WSDLs in such a way that both clients have the same set of folders?

Question

Java

I have two services: Service_1 and Service_2:
First Service:

public class HelloWorldPublisherByServer1 {
  public static void main(String[] args) {
     Endpoint.publish("http://localhost:9999/ws/hello", new HelloWorldImplByService1());
    }
}

Second Service:

public class HelloWorldPublisherByServer2 {
    public static void main(String[] args) {
        Endpoint.publish("http://localhost:9992/ws/hello", new HelloWorldImplByService2());
    }
}

HelloWorldImplByService1 class implementation:

@WebService(endpointInterface = "com.mkyong.ws.first.HelloWorldService1")
public class HelloWorldImplByService1 implements HelloWorldService1 {
 
  @Override
  public String getHelloWorldAsStringByService1(String name) throws MBFault {
    return "111 Hello World JAX-WS " + name;
  }
}

HelloWorldImplByService2 class implementation:

@WebService(endpointInterface = "com.mkyong.ws.second.HelloWorldService2")
public class HelloWorldImplByService2 implements HelloWorldService2 {
    @Override
    public String getHelloWorldAsStringByService2(String name) throws MBFault {
        return "222 Hello World JAX-WS " + name;
    }
}

The HelloWorldImplByService1 and HelloWorldImplByService2 classes are similar.
their methods throw my exception: MBFault.
Implementation of HelloWorldService1 Interface:

@WebService
@SOAPBinding(style = Style.DOCUMENT, use=Use.LITERAL)
public interface HelloWorldService1 {
 	@WebMethod String getHelloWorldAsStringByService1(String name) throws MBFault;
}

The HelloWorldService2 interface is almost identical to the HelloWorldService1 interface.
my MBFault exception is one for both services:

@WebFault(name = "MBFault", targetNamespace = "http://fault.ws.mkyong.com/")
public class MBFault extends Exception {

    private String detail;

    public MBFault(String message, String detail) {
        super(message);
        this.detail = detail;
    }

    public MBFault(String message, String detail, Throwable cause) {
        super(message, cause);
        this.detail = detail;
    }

    public String getDetail() {
        return detail;
    }
}

Based on two services, I can generate two WSDLs and generate two clients,
(using wsimport).
As a result, I get a duplicate of my MBFault exception. How can I avoid duplicating this class?, And is it possible to somehow explicitly specify when creating the service - in which folder the client will be stored, and in which MBFault exception?
