spring-ws does not marshal response message without @XmlRootElement

[rsteppac2]

Dear all,

I am trying to get a spring-ws route (Camel 2.14.0) to populate the SOAP
body of the response without annotating the response class with
@XmlRootElement. I was hoping that by placing an instance of JAXBElement as
the message body this could be done, but no luck.
Unless the @XmlRootElement annotation is present the type conversion in
org.apache.camel.component.spring.ws.SpringWebserviceConsumer::invoke(MessageContext)
fails and returns null. Line 66 ff:

Message responseMessage = exchange.getOut(Message.class);
..
// responseBody is null unless @XmlRootElement is present;
// Source is javax.xml.transform.Source.
Source responseBody = responseMessage.getBody(Source.class); 

I am looking for a way to return "raw values" and generic list types where I
do not even have a class that I could annotate with @XmlRootElement. A
sample ObjectFactory method generated by xjc looks like this:

@XmlElementDecl(namespace = "http://some.org/my/namespace";, name =
"addDelegationResponse")
public JAXBElement<Integer> createAddDelegationResponse(Integer value) {
    return new JAXBElement<Integer>(_AddDelegationResponse_QNAME,
Integer.class, null, value);
}

My route looks like this:

<route id="addDelegation">
    <from
uri="spring-ws:soapaction:http://some.org/my/namespace/addDelegation?endpointMapping=#endpointMapping";
/>
    <setExchangePattern pattern="InOut" />
    <unmarshal ref="jaxb" />
    <bean beanType="ch.vivates.ams.ws.domain.RequestFactory"
method="getDelegation" />
    <enrich uri="vm:pas-put" />
    &lt;!-- ResponseFactory uses ObjectFactory to create JAXBElement --&gt;
    <bean beanType="ch.vivates.ams.ws.domain.ResponseFactory"
method="addDelegationResponse" />
    &lt;!-- Response has empty SOAP body because type conversion fails
--&gt;
</route>

Is there another way to do this with spring-ws?
Changing the WSDL is not really an option for me at this point.


Thanks!
Ralf
