根据本教程，我开发了一个从 Web 服务检索数据的应用程序。
在 Web 服务中，它将获取一些 id 列表并返回 SingleAddWithThumbnail 类对象。
WSDL (JAX-WS)
<xs:element name="getAddCardResponse" type="tns:getAddCardResponse"/>
<xs:element name="getCardDetails" type="tns:getCardDetails"/>
<xs:element name="getCardDetailsResponse" type="tns:getCardDetailsResponse"/>
<xs:complexType name="getAddCard">
<xs:sequence>
<xs:element name="idList" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="getAddCardResponse">
<xs:sequence>
<xs:element name="return" type="tns:singleAddWithThumbnail" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="singleAddWithThumbnail">
<xs:sequence>
<xs:element name="addID" type="xs:string" minOccurs="0"/>
<xs:element name="addTitle" type="xs:string" minOccurs="0"/>
<xs:element name="shopName" type="xs:string" minOccurs="0"/>
<xs:element name="shopNo" type="xs:string" minOccurs="0"/>
<xs:element name="thumbnailPic" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

运行应用程序时会出现这些错误。
