JAX-WS客户端出错/泛型WebService异常

Question

我创建了一个JAX-WS WebService，它应该在身份验证过程中抛出一些业务异常，以便客户端可以处理异常并向用户提供正确的信息。

WS开始在4个月前使用，到那时一切都运行良好，但从那时起我们的客户已经问了很多新功能，合同已经改变了几乎每个开发人员在这里，我无法弄清楚是什么问题。

请问你能帮帮我吗？

@WebService
@ApplicationScoped
public class MyWS {

    @WebMethod
    public MyVO doSomething(parameters...) throws UserAuthenticationException {
        throw new UserAuthenticationException(
            "The message the business guys asked to send..."
        );
    }

现在是Exception类：

public class UserAuthenticationException extends Exception {

    private String details;

    /**
     *
     */
    private static final long serialVersionUID = -3173043626093972452L;

    public UserAuthenticationException(String msg, Throwable t) {
        super(msg, t);
    }

    public UserAuthenticationException(String reason, String details) {
        super(reason);
        this.details = details;
    }

    public UserAuthenticationException(String msg) {
        super(msg);
        this.details = msg;
    }

    public String getFaultInfo() {
        return this.details;
    }
}

在WSDL中可以看到我的异常被映射到一个错误

<portType name="MyWS"><operation name="doSomething"><input message="tns:doSomething" wsam:Action="http://ws.../MyWS/doSomethingRequest">
 ...
    </output><fault name="UserAuthenticationException" message="tns:UserAuthenticationException" wsam:Action="http://ws.../MyWS/doSomething/Fault/UserAuthenticationException">
    </fault></operation>

这是客户端的方法调用，它总是进入catch（WebServiceException e）块

**所有存根/工件都是由WSImport创建的。

public void callMyWs() {
    try {
        //we use a proxy
        MyWS myWsPort = MyWS.getMyWSPort();
        myWsPort.doSomething()

    } catch (UserAuthenticationException_Exception e) {
        JOptionPane.showMessageDialog(e.getMessage());
        ->>>> //Here is where I expect it shoud go...

    } catch (MalformedURLException e) {
        ...
    } catch (WebServiceException e) {
        ...
        //here is where it goes
    } catch (Exception e) {
        ....
    }
}

最后，WSImport使用我的WS方法创建的接口

@WebService(name = "MyWS", targetNamespace = "...")
@XmlSeeAlso({
    ObjectFactory.class
})
public interface MyWS {


    /**
     * 
     * @return
     *     returns MyVO
     * @throws UserAuthenticationException_Exception
     */
    @WebMethod
    @WebResult(targetNamespace = "")
    @RequestWrapper(...", className = "...")
    @ResponseWrapper(localName = "...", targetNamespace = "...", className = "...")
    @Action(input = "...", output = "...", fault = {
        @FaultAction(className = UserAuthenticationException_Exception.class, value = "ws.../MyWS/doSomething/Fault/UserAuthenticationException")
    })
    public MyVO doSomething(params...)
        throws UserAuthenticationException_Exception
    ;

我只是看不出有什么问题

最后，我让它再次运作。

我注意到一些例子在创建代理之前使用QName对象来获取服务实例，所以我试试看它是否有效！

String wsdlUrl = "http://example.com/ns/foo/MyWSService?wsdl"

URL myURL =  new URL(wsdlUrl);
QName myQName = new QName("http://example.com/ns/foo", "MyWSService");

MyWSService service = new MyWSService(myURL, myQName);
