Unmarshalling MTOM message using Camel Spring-WS and JAXB dataformat - jaxb

Question

1) Is there a way to unmarshall MTOM message using Camel Spring-WS component?
2) I tried with Camel JAXB dataformat. It didn't work. Datahandler doesn't have any content. Does JAXB dataformat support MTOM?
<dataFormats>
<jaxb id="jaxb" contextPath="com.mycompany.hr.jaxb"/>
</dataFormats>
<route>
<from uri="spring-ws:rootqname:{http://mycompany.com/hr/schemas}HolidayRequest?endpointMapping=#endpointMapping" />
<unmarshal ref="jaxb"/>
<process ref="testProcessor" />
</route>
3) I thought MTOM is not enabled in JAXB dataformat. So I created a custom dataformat using MTOM enabled JAXB2Marshaller. But still facing the same issue.
import java.io.InputStream;
import java.io.OutputStream;
import javax.xml.transform.Source;
import org.apache.camel.Exchange;
import org.apache.camel.spi.DataFormat;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
public class MtomDataFormat implements DataFormat {
public void marshal(Exchange arg0, Object arg1, OutputStream arg2)
throws Exception {
// TODO Auto-generated method stub
}
public Object unmarshal(Exchange exchange, InputStream is) throws Exception {
Source source = exchange.getContext().getTypeConverter().mandatoryConvertTo(Source.class, is);
Jaxb2Marshaller mar = new Jaxb2Marshaller();
mar.setContextPath("com.mycompany.hr.jaxb");
mar.setMtomEnabled(true);
return mar.unmarshal(source);
}
}
Spring configuration
<bean id="endpointMapping"
class="org.apache.camel.component.spring.ws.bean.CamelEndpointMapping">
</bean>
<bean id="testProcessor" class="TestProcessor" />
<bean id="mtomDataFormat" class="MtomDataFormat" />
<camelContext xmlns="http://camel.apache.org/schema/spring">

<process ref="testProcessor" />
</route>
