Axis2 with MTOM: Unexpected end of stream while reading a SOAP fault

Question

I'm trying to read a soap fault from an axis2 client, with mtom enabled. Axis2 version is 1.6.2, both for client and server.

The wsdl part related to the fault:

 .....

 <xs:simpleType name="CodiceErroreDiTrasferimentoType">
            <xs:annotation>
                <xs:documentation>Codici di errore generati durante il trasferimento del pacchetto di versamento</xs:documentation>

            <xs:restriction base="xs:NMTOKEN">

            </xs:restriction>
        </xs:simpleType>

                            <xs:element name="Codice" type="ingest:CodiceErroreDiTrasferimentoType"/>

                        </xs:sequence>
                    </xs:restriction>
                </xs:complexContent>
            </xs:complexType>
    </xs:element>
....

<wsdl:message name="IngestFault">
    <wsdl:part name="fault" element="ingest:ErroreDiTrasferimento"/>
</wsdl:message>

        <wsdl:output message="tns:InviaPacchettoDiVersamentoResponse"/>
        <wsdl:fault name="IngestFault" message="tns:IngestFault"/>
    </wsdl:operation>

....

    <wsdl:operation name="InviaPacchettoDiVersamento">

        <wsdl:input>

            <soap:fault name="IngestFault" use="literal"/>
        </wsdl:fault>
    </wsdl:operation>

During the reading/parsing of the IngestFault this exception occurs:

The client can successfully read soap message other than soap faults.

Any suggestion? Thanks.

Answer 1

I found the solution: the error occurs when the client cannot parse the SOAP fault because of limitation of axis 2 (in my case it cannot parse the element ErroreDiTrasferimento as a restriction of a complex type) or because the client web service stub is not updated to the current wsdl.

I think the axis exception is not very clear ;)
