關於這個錯誤，本人被困惑了兩天，特別浪費了星期天保貴的休息日。剛才，認真下來分析，嘗試，鈡於被我蒙到了。

在查看網上的相關的信息後，一直以為QNAME與PORT_NAME是targetNamespace的值，並沒有想到是客戶端的接口類包名，如本例中的接口包名“com.webserver.client”.
（本人的服務端與客戶端分屬不同的項目）
所以，記住QNAME與POR_NAME是客戶端的接口類的包名倒寫。

WSDL信息

<wsdl:definitions name="HelloWorld" targetNamespace="http://server.hw.demo/"><wsdl:types><xsd:schema attributeFormDefault="unqualified" elementFormDefault="unqualified" targetNamespace="http://server.hw.demo/"><xsd:element name="sayHi" type="tns:sayHi"/><xsd:complexType name="sayHi"><xsd:sequence><xsd:element minOccurs="0" name="arg0" type="xsd:string"/></xsd:sequence></xsd:complexType><xsd:element name="sayHiResponse" type="tns:sayHiResponse"/><xsd:complexType name="sayHiResponse"><xsd:sequence><xsd:element minOccurs="0" name="return" type="xsd:string"/>

正常運行的代碼

package com.webserver.client;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPBinding;


public final class Client {

    private static final QName SERVICE_NAME 
        = new QName("http://client.webserver.com/", "HelloWorld");
    private static final QName PORT_NAME 
        = new QName("http://client.webserver.com/", "HelloWorldPort");
          //正確的寫法 ，與本地HelloWorld.java接口包名關聯。
 
    private Client() {
    } 

    public static void main(String args[]) throws Exception {
        Service service = Service.create(SERVICE_NAME);
        // Endpoint Address
        String endpointAddress = "http://localhost:8080/first_jaxws/services/HelloWorld?wsdl";

        // Add a port to the Service
        service.addPort(PORT_NAME, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);
        
        HelloWorld hw = service.getPort(HelloWorld.class);
        System.out.println(hw.sayHi("World"));

      /*  User user = new UserImpl("World");
        System.out.println(hw.sayHiToUser(user));

        //say hi to some more users to fill up the map a bit
        user = new UserImpl("Galaxy");
        System.out.println(hw.sayHiToUser(user));

        user = new UserImpl("Universe");
        System.out.println(hw.sayHiToUser(user));

        System.out.println();
        System.out.println("Users: ");
        Map<Integer, User> users = hw.getUsers();
        for (Map.Entry<Integer, User> e : users.entrySet()) {
            System.out.println("  " + e.getKey() + ": " + e.getValue().getName());
        }
*/
    }
