Andreas Veithen updated AXIS-2644:
----------------------------------
Fix Version/s: (was: 1.4)
> Deserializer omits one layer of elements in the response object
> ---------------------------------------------------------------
>
> Key: AXIS-2644
> URL: https://issues.apache.org/jira/browse/AXIS-2644
> Project: Axis
> Issue Type: Bug
> Components: Serialization/Deserialization
> Affects Versions: 1.4
> Environment: Windows XP/JDK1.4
> Reporter: Ping Ning
> Priority: Critical
>
> I define in an XSD a Submission element which contains up to 100 Envelope
> elements but does not have
> any other elements besides the envelopes, i.e., the Submission element is a
> pure wrapper container:
> <xs:element name="Submission">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="Envelope" maxOccurs="100">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="PlanData">
> <xs:complexType>
> <xs:sequence>
>
> <xs:element name="PlanName" type="xs:string">
>
> <xs:element name="PlanStatus" type="xs:string">
> </xs:sequence>
> </xs:complexType>
> </xs:element name="PlanData">
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> The Submission element is used to define a response type in a SOAP message:
> <xs:element name="FilingYearResponse" type="FilingYearResponseType"/>
> <xs:complexType name="FilingYearResponseType">
> <xs:sequence>
> <xs:element ref="sub:Submission"/>
> </xs:sequence>
> </xs:complexType>
> WSDL2Java generates one type SubmissionEnvelope:
> typeDesc.setXmlType(new
> javax.xml.namespace.QName("http://www.pbgc.gov/plan_admin/efiling/Submission";,
> ">>Submission>Envelope"));
> org.apache.axis.description.ElementDesc elemField = new
> org.apache.axis.description.ElementDesc();
> elemField.setFieldName("planData");
> elemField.setXmlName(new
> javax.xml.namespace.QName("http://www.pbgc.gov/plan_admin/efiling/Submission";,
> "PlanData"));
> elemField.setXmlType(new
> javax.xml.namespace.QName("http://www.pbgc.gov/plan_admin/efiling/Submission";,
> ">>>Submission>Envelope>PlanData"));
> elemField.setNillable(false);
> typeDesc.addFieldDesc(elemField);
> The filingYearREsponse object has a getter returning SubmissionEnvelop[].
> The resultant XML message from AXIS is (simplied version without namespace
> etc.):
> <soapenv:Body>
> <FilingYearResponse>
> <Submission>
> <PlanData>
> <PlanName>MyPlanName1</PlanName>
> <PlanStatus>Open</PlanStatus>
> </PlanData>
> </Submission>
> <Submission>
> <PlanData>
> <PlanName>MyPlanName2</PlanName>
> <PlanStatus>Open</PlanStatus>
> </PlanData>
> </Submission>
> </FilingYearResponse>
> </soapenv:Body>
> The Submission and Envelope are collapsed into one layer. What I expect to
> see is:
> <soapenv:Body>
> <FilingYearResponse>
> <Submission>
> <Envelope>
> <PlanData>
> <PlanName>MyPlanName1</PlanName>
> <PlanStatus>Open</PlanStatus>
> </PlanData>
> </Envelope>
> <!--
> </Submission>
> <Submission>
> -->
> <Envelope>
> <PlanData>
> <PlanName>MyPlanName2</PlanName>
> <PlanStatus>Open</PlanStatus>
> </PlanData>
> </Envelope>
> </Submission>
> </FilingYearResponse>
> </soapenv:Body>
> The type mapping seems to have the correct information:
> <typeMapping
> xmlns:ns="http://www.pbgc.gov/plan_admin/efiling/Submission";
> qname="ns:>>Submission>Envelope"
>
> type="java:gov.pbgc.pps.commonservice.types.submission.SubmissionEnvelope"
> serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
> deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
> encodingStyle=""
> />
> The deserializer should create a <Submission> element first, then use the the
> array to create a list of <Envelope>
> elements under this <Submission> element. The meta data seems to be there in
> the type mapping. So my guess is,
> the deserializer does not make use of the meta data properly.
> WSDL2Java could have generated two types, Submission and SubmissionEnvelope.
> FilingYearREsponse contains
> a Submission while the Submission element contains an array of
> SubmissionEnvelope. That would have been cleaner.
> But even with the current WSDL2Java generating only one type, the meta data
> is still sufficient to generate two levels of
> elements (Submission and Envelope) instead of just one (Submission). It's
> certainly much more trickier, because the
> deserializer needs to know about generating Submission as a container for an
> array of SubmissionEnvelopes that are
> mapped to Envelope elements.
> Please let me know if there is any way to get around this. Thanks!
