WebService服务端与客户端的测试问题

最近研究了下WebService，于是想写一个demo测试一下，过程如下：

按照网上写的流程编写服务端代码如下：

@WebService
public class WebServiceDemo {
    public String sayHello(){
        System.out.println("hello");
        return "...";
    }
    public static void main(String[] args){

        Endpoint.publish("http://localhost:8080/two",new WebServiceDemo());
    }
}

找了个干净的文件夹  打开命令行输入了如下命令

wsimport -s . http://localhost:8080/two?wsdl

生成的文件目录如下：

于是另建了一个项目来测试客户端

在客户端项目里新建两个包，将自动生成的.java文件复制到其中一个包里面。

另一个包写客户端代码如下

public class ServiceDemo {
    public static void main(String[] args){
        WebServiceDemo w = new WebServiceDemoService().getWebServiceDemoPort();
        String s = w.sayHello();
        System.err.println(s+":");

    }

}

于是以为万事大吉了，结果运行却报以下错误：

两个字：郁闷，于是开始找原因，研究了半天，重新指定路径让命令行再次自动生成.java类

wsimport -keep -p omc http://localhost:8080/two?wsdl

 

和之前的作对比，发现了只有这两个不同之处...
问题出在了下面这个地方：

生成的文件中这个接口里面这两个className的值，应该改成你客户端的包路径，就是我们把命令行自动生成的.java 文件复制到客户端的时候，这两个className的值应该改成客户端的包目录，改过来之后再次测试，完美解决以上异常。

输出了：

表示调用成功了！
