Can't get JAX-WS binding customization to work
- by Florian
Hi!
I'm trying to resolve a name clash in a wsdl2java mapping with CXF 2.2.6 The relevant wsdl snippets are:
<types>...
<xs:schema...
<xs:element name="GetBPK">
<xs:complexType>
<xs:sequence>
<xs:element name="PersonInfo" type="szr:PersonInfoType" />
<xs:element name="BereichsKennung" type="xs:string" />
<xs:element name="VKZ" type="xs:string" />
<xs:element name="Target" type="szr:FremdBPKRequestType" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="ListMultiplePersons" type="xs:boolean" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="GetBPKResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="GetBPKReturn" type="xs:string" minOccurs="0" />
<xs:element name="FremdBPK" type="szr:FremdBPKType" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="PersonInfo" type="szr:PersonInfoType" minOccurs="0" maxOccurs="5" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
</types>
<message name="GetBPKRequest">
<part name="parameters" element="szr:GetBPK" />
</message>
<message name="GetBPKResponse">
<part name="parameters" element="szr:GetBPKResponse" />
</message>
<binding...
<operation name="GetBPK">
<wsdlsoap:operation soapAction="" />
<input name="GetBPKRequest">
<wsdlsoap:header message="szr:Header" part="SecurityHeader" use="literal" />
<wsdlsoap:body use="literal" />
</input>
<output name="GetBPKResponse">
<wsdlsoap:body use="literal" />
</output>
<fault name="SZRException">
<wsdlsoap:fault use="literal" name="SZRException" />
</fault>
</operation>
As you can see, the GetBPK operation takes a GetBPK as input and returns a GetBPKResponse as an output. Each element of both the GetBPK, as well as the GetBPKResponse type would be mapped to a method parameter in Java. Unfortunately both GetBPK, as well as the GetBPKResponse have an element with the name "PersonInfo", which results in a name clash.
I'm trying to resolve that using a binding customization:
<jaxws:bindings wsdlLocation="SZ2-aktuell.wsdl"
xmlns:jaxws="http://java.sun.com/xml/ns/jaxws" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:szr="urn:SZRServices">
<jaxws:bindings
node="wsdl:definitions/wsdl:portType[@name='SZR']/wsdl:operation[@name='GetBPK']">
<!-- See page 116 of the JAX-WS specification version 2.2 from 10, Dec 2009 -->
<jaxws:parameter
part="wsdl:definitions/wsdl:message[@name='GetBPKResponse']/wsdl:part[@name='parameters']"
childElementName="szr:PersonInfoType" name="PersonInfoParam" />
</jaxws:bindings>
</jaxws:bindings>
and call wsdl2java with the -b parameter. Unforunately, I still get the message:
WSDLToJava Error: Parameter: personInfo already exists for method getBPK but of type at.enno.egovds.szr.PersonInfoType instead of java.util.List<at.enno.egovds.szr.PersonInfoType>. Use a JAXWS/JAXB binding customization to rename the parameter.
I have tried several variants of the binding customization, and searched Google for hours, but unfortunately I cannot find a solution to my problem.
I suspenct that the childElementName attribute is wrong, but I can't find an example of what would have to be set to make it work.
Thanks in advance!
