    Default Client received SOAP Fault from server: java.lang.NullPointerException

    I'm writing my first JAX-WS Web Service. When I'm running my Remote Web Service Client code, I receive the next error:
    Exception in thread "main" com.sun.xml.internal.ws.fault.ServerSOAPFaultExcep tion: Client received SOAP Fault from server:
    java.lang.NullPointerException Please see the server log to find more detail regarding exact cause of the failure. at

    org.example.shoesshop.client.ShoesServiceClient.ma in(ShoesServiceClient.java:32)
    Here's the code of Remote Web Service Client:
    public class ShoesServiceClient {
     
        public static void main(String[] args) throws MalformedURLException, ShoesNotFound_Exception{
            System.setProperty("com. sun. xml. ws. transport. http. client. HttpTransportPipe. dump", "true");
            System.setProperty("com. sun. xml. internal. ws. transport. http. client. HttpTransportPipe. dump", "true");
     
            URL wsdl = new URL("file:///" + new File("").getAbsolutePath() + "/shoesservice.wsdl");
     
            ShoesServiceImpl service = new ShoesService(wsdl).getShoesPort();
            service.getShoes(1); // ShoesServiceClient.java:32 is here
        }
    }

    Also sharing the code of Web Service Publisher
    public class ShoesServicePublisher {
        public static void main(String[] args) {
            final String addr = "localhost: 8080 /shoesservice"; //with http
            final Object impl = new ShoesServiceImpl();
            Endpoint shoesPub = Endpoint.publish(addr, impl);
            Scanner sc = new Scanner(System.in);
            sc.nextLine();
            sc.close();
            shoesPub.stop();
        }
    }

    I use TCP/IP monitor to intercept messages (localhost: 18080 /shoesservice)
    The wsdl-file has the next structure (it is stored on my project folder)
    <definitions>

    When I launch the TCP/IP Monitor with running Remote Web Service Client code, I get the next messages in XML format:

    Request Message
    <?xml version="1.0"  standalone="no"?>
    <S:Envelope xmlns:S="schemas. xmlsoap. org/soap/envelope/">
    <S:Body>
    <ns3:getShoes xmlns:ns2="example.org/ShoesShop" xmlns:ns3="shoeshop.example/jaxws/shoes">
    <arg0>1</arg0>
    </ns3:getShoes>
    </S:Body>
    </S:Envelope>

    Response Message
    <?xml version="1.0"  standalone="no"?>
    <S:Envelope xmlns:S="schemas. xmlsoap. org/soap/envelope/">
    <S:Body>
    <S:Fault xmlns:ns4="w3.org/2003/05/soap-envelope">
    <faultcode>S:Server</faultcode>
    <faultstring>java.lang.NullPointerException</faultstring>
    </S:Fault>
    </S:Body>
    </S:Envelope>

    If you need for information, please let me know
