如何将null值传递给文档文本SOAP请求

Question

嗨，我在SOAP请求中传递resourcekey的null值，如下所示。

 <urn:createNetwork>
 <net:resourceIdentityInfo>
        <api:resourceKey ></api:resourceKey>
           <api:resourceName>TEST2</api:resourceName>
           <api:resourceType>NETWORK</api:resourceType>
 </net:resourceIdentityInfo>
 </urn:createNetwork>

此请求的示例WSDL文件如下所示：

 <wsdl:operation name="createNetwork">

     <wsdlsoap:operation soapAction=""/>

     <wsdl:input name="createNetworkRequest">

        <wsdlsoap:body use="literal"/>

     </wsdl:input>

     <wsdl:output name="createNetworkResponse">

        <wsdlsoap:body use="literal"/>

     </wsdl:output>

      </wsdl:operation>

  <element name="createNetwork">
 <complexType>
 <sequence>
  <element name="in0" type="tns5:NetworkInfo"/>
 </sequence>
</complexType>
 </element>
 <element name="createNetworkResponse">
 <complexType>
 <sequence>
  <element name="createNetworkReturn" type="tns2:ResourceIdentityInfo"/>
 </sequence>
</complexType>
</element>
<wsdl:message name="createNetworkRequest">
  <wsdl:part element="intf:createNetwork" name="parameters">
  </wsdl:part>
</wsdl:message>
 <complexType name="NetworkInfo">
<sequence>
 <element name="comments" nillable="true" type="impl:ArrayOf_xsd_anyType"/>
 <element name="description" nillable="true" type="xsd:string"/>
 <element name="dnsDomainName" nillable="true" type="xsd:string"/>
 <element name="documentUrls" nillable="true" type="impl:ArrayOf_xsd_anyType"/>
 <element name="resourceIdentityInfo" nillable="true" type="tns2:ResourceIdentityInfo"/>
</sequence>
</complexType>
<complexType name="ResourceIdentityInfo">
<sequence>
 <element name="resourceKey"  nillable="true" type="xsd:string"/>
 <element name="resourceName" nillable="true" type="xsd:string"/>
 <element name="resourceType" nillable="true" type="xsd:string"/>
</sequence>
</complexType>

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"   xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
  <soapenv:Fault>
     <faultcode>soapenv:Server.userException</faultcode>
     <faultstring>java.lang.NullPointerException</faultstring>
     <detail>
        <ns1:hostname   xmlns:ns1="http://xml.apache.org/axis/">linbgg244.lss.emc.com</ns1:hostname>
     </detail>
  </soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

<api:resourceKey xsi:nil="true" ></api:resourceKey> 

提前谢了。

我认为这里不必传递null。AFAIK中，webservice代码在处理SOAP请求期间抛出NullPointerException。试着找出这是为什么？并执行null检查或更改逻辑以防止发生这种情况。
