WebFault和Web Service在不同的命名空间中

Question

我需要在不同的命名空间中定义自定义异常而不是Web服务。但是当我生成一个wsdl时，一些包装器出现在webservice的命名空间中。是否可以在没有此包装器的情况下使用来自另一个命名空间的异常？

例外：

@WebFault(targetNamespace = "http://somenamespace/server/faults",
faultBean = "my.package.SoapBadRequestException.FaultBean")
    public class SoapBadRequestException extends Exception {
    private FaultBean faultBean;

    @XmlType(name = "FaultBean", namespace = "http://somenamespace/server/faults")
    public static class FaultBean {}

    public SoapBadRequestException() { super(); }

    public SoapBadRequestException(String message, FaultBean faultBean, Throwable cause) {
        super(message, cause);
        this.faultBean = faultBean;
    }

    public SoapBadRequestException(String message, FaultBean faultBean) {
        super(message);
        this.faultBean = faultBean;
    }

    public FaultBean getFaultInfo() { return faultBean; }
}

网络服务：

@WebService(targetNamespace = "http://somenamespace/server/ws")
public interface MyWebService {

void someOperation(
        @WebParam(name = "param1") String param1,
        @WebParam(name = "param2") String param2) throws SoapBadRequestException;
}

产生的wsdl（FaultBean未定义，也不知道原因）：

我看到this和this但没有任何帮助。
