You should set the HTTP status code to an appropriate value, in the 400 or 500 range, via getResponse().setStatus(). See http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10. For your example, 401 Bad Request would be appropriate.
You can also return a representation that may return additional context information about the error, but there are no REST standards for this; the status code itself should be enough for the client to intelligently interpret. In Resource.put(), you'd return a Representation object after you set the response status code. ..
