'IllegalArgumentException: SOAPElement expected' with XmlBeans

[Szpak]

Hi,

I use XmlBeans (2.3.0) as a (un)marshaller in Spring Web Services. A request is properly processed, but returned response causes:

2007-09-23 17:41:41,015 DEBUG [org.myname.webservice.ChangeUserPasswordMarshallingEndpoint] Marshalling [<ChangeUserPas
swordResponse xmlns="http://www.myname.org/schemas">

Response displayed above an exception by an interceptor looks ok.

My endpoint is very simple:

public class ChangeUserPasswordMarshallingEndpoint extends AbstractMarshallingPayloadEndpoint {

    public ChangeUserPasswordMarshallingEndpoint(Marshaller marshaller) {
        super(marshaller);
    }

    protected Object invokeInternal(Object object) throws Exception {
        ChangeUserPasswordRequestDocument cupReqDoc = (ChangeUserPasswordRequestDocument) object;
        ChangeUserPasswordRequestDocument.ChangeUserPasswordRequest cupReq = cupReqDoc.getChangeUserPasswordRequest();

        /* ... */

        ChangeUserPasswordResponseDocument cupResDoc = ChangeUserPasswordResponseDocument.Factory.newInstaclassnce();
        ChangeUserPasswordResponseDocument.ChangeUserPasswordResponse cupRes = cupResDoc.addNewChangeUserPasswordResponse();
        cupRes.setToken("whatTheHellIsIt");
        return cupResDoc;
    }

Mentioned ChangeUserPassword classes was generated from xsd:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
        elementFormDefault="qualified"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        targetNamespace="http://www.myname.org/schemas"
        xmlns:ss="http://www.myname.org/schemas">

    <!-- ... -->
    <xs:element name="ChangeUserPasswordResponse">
        <xs:complexType>
            <xs:all>
                <xs:element name="Token" type="xsd:string"/>
            </xs:all>
        </xs:complexType>
    </xs:element>
</xs:schema>

My Spring-WS configuration:

    <bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
        <property name="mappings">
            <props>
                <prop key="{http://www.myname.org/schemas}ChangeUserPasswordRequest">changeUserPasswordMarshallingEndpoint</prop>
            </props>
        </property>
        <property name="interceptors">
            <bean class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor"/>
        </property>
    </bean>

    <bean id="changeUserPasswordMarshallingEndpoint" class="org.myname.spotspam.webservice.ChangeUserPasswordMarshallingEndpoint">
        <constructor-arg ref="marshaller"/>
    </bean>

    <bean id="marshaller" class="org.springframework.oxm.xmlbeans.XmlBeansMarshaller"/>

Do you know what can cause the problem?

Once again SAAJ in JBoss was a problem.
