> I'm attaching my sample jaxws service and its source code.
> In JAXWS services, body and header parts are kept as
> org.apache.axis2.jaxws.message.impl.BlockImpl objects. These message blocks
> are read before invoking the service and all are set as "consumed".
> But in this sample service, I want to access Reference Parameters and I've
> done that using the following line.
> List<Element> referenceParam = (List<Element>)
> context.getMessageContext().get(MessageContext.REFERENCE_PARAMETERS);
> And also this service is expecting a header which is called "TestHeader" and
> it is already consumed when the execution comes into the service. But above
> access to reference parameters calls the getXMLStreamReader of the BlockInmpl
> object of the header block. As it is already consumed, it gives the following
> exception.
> Caused by: javax.xml.ws.WebServiceException: An internal error occurred. The
> org.apache.axis2.jaxws.message.databinding.impl.JAXBBlockImpl block object is
> already consumed. Processing cannot continue. Run with the debug option to
> determine where the block was first consumed.
