我指的是某人代码，当他们像sdServices.topup（null，null，null，topupRequest）那样调用时，并没有获得以下代码的确切含义作为抛出错误
@WebMethod(operationName = "Topup")
@WebResult(name = "topupResponse", targetNamespace = "http://www.utiba.com/xml/ns/sdp/soap/service/v3", partName = "TopupResponse")
public StandardResponse topup(
@WebParam(partName = "ClientId", name = "clientId", targetNamespace = "http://www.utiba.com/xml/ns/sdp/soap/service/v3", header = true)
java.lang.String clientId,
@WebParam(partName = "TerminalId", name = "terminalId", targetNamespace = "http://www.utiba.com/xml/ns/sdp/soap/service/v3", header = true)
java.lang.String terminalId,
@WebParam(partName = "CardData", name = "cardData", targetNamespace = "http://www.amdocs.com/xml/ns/card/soap/v1", header = true)
com.amdocs.xml.ns.card.soap.v1.CardData cardData,
@WebParam(partName = "TopupRequest", name = "topupRequest", targetNamespace = "http://www.utiba.com/xml/ns/sdp/soap/service/v3")
TopupRequest topupRequest
) throws SDPValidationFault_Exception, SDPFault_Exception;
