如何在Java Web服务中重载方法？

@WebMethod()
public Long addNewApplication(String applicationName) throws ServiceManagerException {
    // implementation
}

@WebMethod()
public Long addNewApplication(String applicationName,ApplicationState status) throws ServiceManagerException {
    // implementation
}

问题是上面不起作用,我得到以下异常：

org.springframework.remoting.jaxws.JaxWsSoapFaultException: Cannot find dispatch method for Request=[SOAPAction="",Payload={http://example.org/applicationManager}addNewApplication]; nested exception is javax.xml.ws.soap.SOAPFaultException: Cannot find dispatch method for Request=[SOAPAction="",Payload={http://example.org/applicationManager}addNewApplication]

如果我重命名方法以便它们具有不同的名称,那么一切都有效.是否可以在Web Service中使用重载方法？如果是,那怎么样？
