Response response = exchange.getIn().getHeader(RestletConstants.RESTLET_RESPONSE, Response.class);

response.setStatus(Status.SUCCESS_NO_CONTENT);

response.setLocationRef("http://localhost:8887/IVRInterface/CreateShiftRequestTypes(0)");

exchange.getOut().setHeader(RestletConstants.RESTLET_RESPONSE, response);

exchange.getOut().setHeader("LocationRef","http://localhost:8887/IVRInterface/CreateShiftRequestTypes(0)");

I have tried to use this code as well but it does not recognise Header.class:

ConcurrentMap)

        attrs.putIfAbsent(HeaderConstants.ATTRIBUTE_HEADERS, headers);

    if (prev != null) { headers = prev; }

}

headers.add("location", "myHeaderValue");
