Hi Rob, That was new to me, thanks for bringing that to our attention as it might be a common issue. It would help to ask to Tomcat team about the reasons of this behavior. AFAICT, the Restlet/Servlet mapping looks fine, I'm not aware about any such restriction in Servlet API, regarding absence of entity. Any other thought?

The two acute places this is obvious is with 304 Not Modified responses and with the OPTIONS response. Tomcat returns a 200 OK with some default headers, instead of passing the correct header set and no entity emerging from Restlet. I verified that the version of Tomcat embedded in GWT 1.4 exhibits the problem, but haven't yet verified it in other places. The workaround (which will cause Restlet 1.1 to gripe, but works) is to emit an entity anyway, when none is called for, e.g. new StringRepresentation("This entity is not changed",MediaType.TEXT_HTML); In my application, I keyed this to a system property so that the non-compliant behavior can be turned on only when needed. Someone who is more knowledgeable than I am about the Servlet extension may be able to figure out if this is a Restlet bug or not.

The Allow: header of the response is populated, and I tracked it all the way down through ServletCall and verified Restlet is doing the right thing. But, the OPTIONS response sent to the client from Tomcat is stripped of this and other useful headers (like DAV: 1,2).
