> I have a problem with jibx databinding in webservises built with Axis2.
> My part built with the mentioned frameworks is contacting remote
> implementation of webservices. Remote webservises are built with very
> different frameworks and are working without any problems. They responce on
> my webservice request with XML like shown below (i've renamed namespaces and
> stripped lots of unimportant fields):
> ---8<--------------------
> <ns2:AResponse
> xmlns="http://www.my.com/common";
> xmlns:ns2="http://www.my.com/request";
> xmlns:ns6="http://www.my.com/response";
> <ns6:ResponseState>
> <ErrorCode>0</ErrorCode>
> <StrErrorCode
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:nil="true"/>
> <Message>Success</Message>
> <NativeError
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:nil="true"/>
> <LogSequence
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:nil="true"/>
> </ns6:ResponseState>
> </ns2:AResponse>
> -------------------->8---
> The appropirate part of XSD from appropriate webservice definition should
> look like:
> ---8<--------------------
> <?xml version="1.0" encoding="UTF-8"?>
> <xsd:schema
> targetNamespace="http://www.my.com/common";
> xmlns="http://www.my.com/common";
> xmlns:xsd="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified">
> ...
> <xsd:complexType name="ResponseStateType">
> <xsd:sequence>
> <xsd:element name="ErrorCode" type="xsd:int" minOccurs="1"
> nillable="false" />
> <xsd:element name="StrErrorCode" type="xsd:string" minOccurs="0"
> nillable="true" />
> <xsd:element name="Message" type="xsd:string" minOccurs="1"
> nillable="false" />
> <xsd:element name="NativeError" type="xsd:string" minOccurs="0"
> nillable="true" />
> <xsd:element name="LogSequence" type="xsd:long" minOccurs="0"
> nillable="true" />
> </xsd:sequence>
> </xsd:complexType>
> ...
> </xsd:schema>
> -------------------->8---
> And my binding.xml then looks like (a bit complicated due to original
> namespaces hierarhy):
> ---8<--------------------
> <mapping
> name="AResponse"
> class="com.my.FileInfoSearchResult"
> extends="com.my.PageableSearchResult">
> <namespace uri="http://www.my.com/request"; default="elements" />
> <structure map-as="com.my.PageableSearchResult" />
> </mapping>
> <mapping abstract="true" class="com.my.PageableSearchResult">
> <namespace prefix="lr" uri="http://www.my.com/response";
> default="elements"/>
> <structure name="ResponseState" field="responseState" usage="required"
> type="com.my.ResponseStateType"/>
> </mapping>
> <mapping abstract="true" class="com.my.ResponseStateType">
> <namespace prefix="respst" uri="http://www.my.com/common";
> default="elements"/>
> <value name="ErrorCode" field="errorCode" usage="required"/>
> <value name="StrErrorCode" field="strErrorCode" nillable="true"
> usage="optional"/>
> <value name="Message" field="message" usage="required"/>
> <value name="NativeError" field="nativeError" nillable="true"
> usage="optional"/>
> <value name="LogSequence" field="logSequence" nillable="true"
> usage="optional"/>
> </mapping>

> The problem is in the fact that unmarshaling of the webservces response on my
> side fails. The original exception is:
> ---8<--------------------
> "IllegalStateException: Current state not START_ELEMENT"
> -------------------->8---
> Then the exception is wrapped into AxisFault when being thown out.
> The IllegalStateException is thrown from the place shown in this stacktrace
> (stopped on "IllegalStateException trow" breakpoint):

> An must note that value of mCurrToken is END_ELEMENT. I think that the code
