How to get WSDL operation name from SoapMessage in CXF Request Interceptor

Im trying to get wsdl operation name (SOAPAction) but it gives me null. i have written a request interceptor in camel blueprint.
TASK TO DO: Aim is to intercept the webservice request retrieve username & password from headers & check whether the user have have rights to consume the requested SOAPAction/OperationName. How can i achieve this.? Is there any other approach to do this.

public class Interceptor extends AbstractSoapInterceptor {

    Logger _log = Logger.getLogger(Interceptor.class);

    public Interceptor() {
        super(Phase.PRE_LOGICAL);
    }

    @Override
    public void handleMessage(SoapMessage message) {
        _log.info(".... IM HERE INTERCEPTOR");

        Map<String, List<String>> headers = CastUtils.cast((Map) message.get(Message.PROTOCOL_HEADERS));
        _log.info(".... IM HERE INTERCEPTOR:::: " + headers.size());

        for (Entry<String, List<String>> entry : headers.entrySet()) {
            _log.info(entry.getKey() + " /// " + entry.getValue().get(0));
        }
    }
}

Logs of my code are here:

.... IM HERE INTERCEPTOR
.... IM HERE INTERCEPTOR:::: 9
accept-encoding /// gzip,deflate
connection /// keep-alive
Content-Length /// 351
content-type /// text/xml;charset=UTF-8
Host /// localhost:8181
password /// herman
SOAPAction /// ""
User-Agent /// Apache-HttpClient/4.1.1 (java 1.5)
username /// herman

Below is Blueprint

            <to id="_to1" uri="log:output"/>
        </route>
    </camelContext>
</blueprint>

here is the solution :)

@Override
public void handleMessage(SoapMessage message) {
    _log.info(".... IM HERE INTERCEPTOR");

    HttpServletRequest httpRequest = (HttpServletRequest) message.get(AbstractHTTPDestination.HTTP_REQUEST);

    Message inMessage = message.getExchange().getInMessage();
    MessageInfo mi = (MessageInfo) inMessage.get(MessageInfo.class);
    OperationInfo operationInfo = mi.getOperation();

    _log.info("username:: " + httpRequest.getHeader("username"));
    _log.info("password:: " + httpRequest.getHeader("password"));

    if (operationInfo != null) {
        _log.info("operationInfo:: " + operationInfo.getInputName());
    }
}

logs:

username:: herman
password:: herman
operationInfo:: getQuery
