Question

我创建了两项服务public String add(int x, int y)和public String sub(int x, int y)。现在，这些服务的定义如下：

package com.webservice.calc;

import javax.jws.WebService;;

@WebService
public class Calculator {

    String s;
    public String add(int x, int y)
    {
        s = "Sum of "+x+" and "+y+" is : "+(x+y);
        return s;
    }

    public String sub(int x, int y)
    {
        s = "Sum of "+x+" and "+y+" is : "+(x-y);
        return s;
    }
}

我没有写差异，而是在sub服务中写了 Sum 。

然后我用 wsgen 工具生成wsdl文件并使用Endpoint发布者，我发布了它。

然后，我创建了另一个项目（Web Service Consumer）并使用 wsimport 导入了Web服务。

代码很好。但是，现在我想将 Sum 更改为差异。

我更改了原始代码中的代码，然后使用 wsgen ，然后重新发布（这里出现了错误：

）然后再次导入它。但没有变化。这是什么问题？

修改源代码并重新生成Web Service时，JAX-WS Web Service不会更新
