在 Web 服务客户端上运行简单功能时 Eclipse 出错

Question

我只想首先为我的英语不太好道歉。 我正在为 Enterprise Java Developers 版本 4.17.0 开发 Eclipse IDE，我也在使用 Apache Tomcat v9.0 和 axis2-1.7.9。我正在尝试在我的客户端 Web 服务上执行一个简单的求和函数，但我遇到了这个错误：

package org.apache.ws.axis2;

import java.rmi.RemoteException;

import org.apache.axis2.AxisFault;
import org.apache.ws.axis2.CalculStub.Somme;

public class TesrClient {

    public static void main(String[] args) throws RemoteException {
        // TODO Auto-generated method stub
        CalculStub stub = new CalculStub();
        Somme somme0 = new Somme();
        somme0.setX(10);
        somme0.setY(20);
        int res = stub.somme(somme0).get_return();
        System.out.println("la somme est : " + res);
    }

}

这是控制台日志：

似乎是什么问题？

编辑： 这是 CalculStub.java 文件，它太长了，所以我不得不粘贴到在线剪贴板中：https://cl1p.net/calculstub

关键是堆栈跟踪顶部的以下内容：

CalculStub.Somme 类型必须实现继承的抽象方法 ADBBean.serialize(QName, XMLStreamWriter)

您没有向我们展示“CalculStub”类，但我猜它直接或间接扩展了“ADBBean”类。

在 Java 编程中，可用于创建实例的具体类（使用“new”运算符）必须具有任何抽象方法的实现。错误消息说“CalculStub”类需要有“serialize”方法的具体实现，但它没有。
