Hi all,
I have a big problem with Axis: I need to make an Axis client communicate
with a gSOAP C server hosting my web service. Both of them are generated
from the same WSDL document, and they are both rpc/litteral (I didn't choose
it, the gSOAP server is already implemented and I can't modify it).
My problem is the following: my axis client launches the request, my gSOAP
server processes it without difficulty, but when it receives the response my
client raises the following exception:
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: org.xml.sax.SAXException: Invalid element in
com.project.ListOfAURO - AffiliateUserRequestOutput
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXException:
Invalid element in com.project.ListOfAURO - AffiliateUserRequestOutput

Here come the interesting parts of the WSDL I use:
These are the 2 OUT parameters of my method AffiliateUser:
<xsd:simpleType name="GECReport">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="GEC_OK"/>
<xsd:enumeration value="GEC_GenericErrorCode"/>
<xsd:enumeration value="GEC_DataBaseError"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:complexType name="ListOfAURO">
<xsd:sequence>
<xsd:element name="AffiliateUserRequestOutput"
type="lns:AffiliateUserRequestOutput"
maxOccurs ="unbounded"
minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="AUReport">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="AU_OK"/>
<xsd:enumeration value="AU_AffiliationFailed"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:complexType name="AffiliateUserRequestOutput">
<xsd:sequence>
<xsd:element name="UserSymbolicAddress" type="xsd:string"/>
<xsd:element name="AffiliationReport" type="lns:AUReport"/>
</xsd:sequence>
</xsd:complexType>
The Request and Response messages:
<wsdl:message name="AffiliateUser">
<wsdl:part
name="ServiceType"
type="rns:Service"/>
<wsdl:part
name="ListOfInputParameters"
type="lns:ListOfAUIP"/>
</wsdl:message>
<wsdl:message name="AffiliateUserResponse">
<wsdl:part
name="ListOfOutputParameters"
type="lns:ListOfAURO"/>
<wsdl:part
name="return"
type="lns:GECReport"/>
</wsdl:message>
<wsdl:portType name="Project-Interface">
<wsdl:operation name="AffiliateUser">
<wsdl:input message="lns:AffiliateUser"/>
<wsdl:output message="lns:AffiliateUserResponse"/>
</wsdl:operation>
</wsdl:portType>
The messages (both request and response) seem to be well-formed.
After some researches in the mailing-list archives I tried to change the
WSDL and use low case strings like this:
<xsd:complexType name="AffiliateUserRequestOutput">
<xsd:sequence>
<xsd:element name="userSymbolicAddress" type="xsd:string"/>
<xsd:element name="affiliationReport" type="lns:AUReport"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="ListOfAURO">
<xsd:sequence>
<xsd:element name="affiliateUserRequestOutput"
type="lns:AffiliateUserRequestOutput"
maxOccurs ="unbounded"
minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
<wsdl:message name="AffiliateUser">
<wsdl:part
name="ServiceType"
type="ips:Service"/>
<wsdl:part
name="ListOfInputParameters"
type="lns:ListOfAUIP"/>
</wsdl:message>
<wsdl:message name="AffiliateUserResponse">
<wsdl:part
name="listOfOutputParameters"
type="lns:ListOfAURO"/>
<wsdl:part
name="return"
type="lns:GECReport"/>
</wsdl:message>
With this configuration on both sides, I don't have the exception but when I
try to access the holders' attributes, it raises a
java.lang.NullPointerException...
Here is a part of my client code with the way I deal with the holders:
// ListOfAUROHolder
// just one user
AffiliateUserRequestOutput affiliateUserRequestOutput = new
AffiliateUserRequestOutput();
AffiliateUserRequestOutput[] affiliateUserRequestOutputArray = new
AffiliateUserRequestOutput[1];
affiliateUserRequestOutputArray[0] = affiliateUserRequestOutput;
ListOfAUROHolder listOfOutputParameters = new ListOfAUROHolder(new
ListOfAURO(affiliateUserRequestOutputArray));
// GECReportHolder
GECReportHolder _return = new GECReportHolder();
// Make the actual call
locPort.affiliateUser(Service.fromValue(serviceType), listOfInputParameters,
listOfOutputParameters, _return);
ListOfAURO listOfAURO = listOfOutputParameters.value;
AffiliateUserRequestOutput[] auro =
listOfAURO.getAffiliateUserRequestOutput();
This line raises the exception.
Here is the signature of ListOfAURO class:
public class ListOfAURO implements java.io.Serializable {
private com.thalesgroup.IPS.LOC_xSV.AffiliateUserRequestOutput[]
affiliateUserRequestOutput;
Can anyone help me ? Do I have missed something with holders ? When I use my
client with a fake Axis server, there is no problem...
Thanks.
Laurent
