webservice 无法将 System.Xml.XmlNode[] 类型的对象分配给 System.String 类型的对象
我正在尝试使用 Visual Basic.net 使用 Java Web 服务。我在反序列化时收到错误“无法将 System.Xml.XmlNode[] 类型的对象分配给 System.String 类型的对象”。
我一直在读的是 wsdl 规范可能不符合 WS-I BP 1.1 规范。 链接
另一个解决方案谈到了这里是更改响应xml以符合.net数据类型。几年前,我曾出于其他原因尝试这样做,但事实证明它不稳定。
wsdl 的一个片段如下:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:impl="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:intf="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:tns2="http://io.datainfo.APILink.amdocs"
xmlns:tns3="http://datainfo.APILink.amdocs"
xmlns:tns4="http://awsi.amdocs.com"
xmlns:tns5="http://exceptions.APILink.amdocs"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<complexType name="InPersonInfo">
<complexContent>
<extension base="tns2:BaseInputOutputInfo">
<sequence>
<element maxOccurs="1" minOccurs="0" name="mItem1" type="xsd:int"/>
<element maxOccurs="1" minOccurs="0" name="mID" nillable="true" type="xsd:string"/>
<element maxOccurs="1" minOccurs="0" name="mPersonType" type="tns4:char"/>
</sequence>
</extension>
</complexContent>
</complexType>
我看到的 WSDL 中的其他部分只是消息和操作部分。
编辑2011-04-21:这个问题提到了我正在经历的事情。
我不熟悉 java,我知道它是使用 AXIS 或 SOAPUI 创建/使用的,并且不知何故它没有根据标准创建 WSDL,这就是我的问题。如果我找到解决该问题的答案,我会将其发布在这里。
I am trying to consume a Java Webservice using Visual Basic.net. I am getting an error on deserialization "Cannot assign object of type System.Xml.XmlNode[] to an object of type System.String".
What I have been reading is that the wsdl specification may not conform to the WS-I BP 1.1 specification. Link Here
The other solution talked about here is to change the response xml to conform to a .net datatype. I have tried to do this for other reasons a couple of years back and it proved to be unstable.
A snippet of the wsdl is this:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:impl="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:intf="http://ws.interfaces.sessions.APILink.amdocs"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:tns2="http://io.datainfo.APILink.amdocs"
xmlns:tns3="http://datainfo.APILink.amdocs"
xmlns:tns4="http://awsi.amdocs.com"
xmlns:tns5="http://exceptions.APILink.amdocs"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<complexType name="InPersonInfo">
<complexContent>
<extension base="tns2:BaseInputOutputInfo">
<sequence>
<element maxOccurs="1" minOccurs="0" name="mItem1" type="xsd:int"/>
<element maxOccurs="1" minOccurs="0" name="mID" nillable="true" type="xsd:string"/>
<element maxOccurs="1" minOccurs="0" name="mPersonType" type="tns4:char"/>
</sequence>
</extension>
</complexContent>
</complexType>
The other pieces from the WSDL I am seeing is just the message and operation sections.
EDIT 2011-04-21: This question mentions what I am going through.
I am not familiar with java what I know is that it is being created/consumed with AXIS or SOAPUI and somehow it is not creating the WSDL according to standard and there is my problem. If I find an answer to solve it I will post it here.
