Was sind die Ursachen einer “org.xml.sax.SAXException: Bad types" Ausnahme beim aufrufen einer ColdFusion-Web-Service?

Ich geschrieben habe, eine ColdFusion-Web-Service für einen externen client, um zu konsumieren. Es ist im Grunde lassen Sie uns Sie senden über einige Benutzer-Informationen, und liefert den Inhalt der Benutzer in den Einkaufswagen legen, und lassen Sie Elemente hinzufügen, um den Benutzer in den Einkaufswagen legen. Der Einfachheit halber, werden wir gerade die "getCart" - Methode.

Müssen Sie den Web-Service für die Rückkehr von Xml im SOAP-Umschlag, aber Sie müssen auch in Xml enthalten spezifische komplexe Datentypen. Zum Beispiel, jeden Wunsch zurückgeben muss, die einen status-code und die Nachricht, die als Teil einer ReturnInfo geben. So, ich habe geschrieben eine hart-codierte WSDL für Sie zu konsumieren, mit der komplexe Datentypen beschrieben, die innerhalb (der ich im Grunde nahm die ColdFusion-generierte WSDL und bearbeitet es):

Jeden Anruf Sie machen, um entweder die Web-Service-damit Sie die gleichen Fehler:
