轴网络服务错误

我编写了一个简单的java文件Calculator.java，如下所示

public class Calculator {
    public int add(int a, int b) {
        return a+b;
    }
    public int subtract(int a, int b) {
        return a-b;
    }
}

现在，我将其重命名为Calculator.jws并将其放在我的Web应用程序的根目录中。（与 WEB-INF 目录位于同一目录中）。当我尝试使用 http://localhost:8680/webappcontextroot/Calculator.jws 我收到一条消息，显示

“此处有一个 Web 服务。单击查看 WSDL”

当我单击链接查看 WSDL 文件时，出现错误，

AXIS 错误

无法生成 WSDL！

此位置没有 SOAP 服务

当我编写客户端来调用 Web 服务时，出现 Axis 错误

- Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.
Exception in thread "main" AxisFault
 faultCode: {http://xml.apache.org/axis/}Server.NoService
 faultSubcode: 
 faultString: The AXIS engine could not find a target service to invoke!  targetService is null
 faultActor: 
 faultNode: 
 faultDetail: 
    {http://xml.apache.org/axis/}hostname:D78D46BS

AXIS 引擎找不到要调用的目标服务！ targetService is null

WSDL 文件似乎丢失；但 oreilly 教程告诉您只需将 java 文件复制到 .jws 文件并将其放入您的 Web 应用程序中，Web 服务就可以使用了。

有人可以帮我解决这个问题吗？

原文

I have written a simple java file Calculator.java as below

public class Calculator {
    public int add(int a, int b) {
        return a+b;
    }
    public int subtract(int a, int b) {
        return a-b;
    }
}

Now, i renamed it to Calculator.jws and put it in my web application's root directory. (in the same directory as the WEB-INF directory). When i try to access this webservice using http://localhost:8680/webappcontextroot/Calculator.jws i get a message saying

"There is a Web Service here. Click to see the WSDL"

When i click on the link to see the WSDL file i get an error,

AXIS error

Could not generate WSDL!

There is no SOAP service at this location

When i wrote a client to invoke the web service, i get an Axis fault

- Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.
Exception in thread "main" AxisFault
 faultCode: {http://xml.apache.org/axis/}Server.NoService
 faultSubcode: 
 faultString: The AXIS engine could not find a target service to invoke!  targetService is null
 faultActor: 
 faultNode: 
 faultDetail: 
    {http://xml.apache.org/axis/}hostname:D78D46BS

The AXIS engine could not find a target service to invoke! targetService is null

The WSDL file seems to be missing; but the oreilly tutorial tells all you have to do is just copy your java file to a .jws file and put it in your webapp and the webservice is ready to use.

Can someone help me with this?
