Class JacksonRepresentation (from Restlet's Jackson extension) creates an ObjectMapper with the AUTO_CLOSE_TARGET disabled. I extended JacksonRepresentation to override createObjectMapper in order to do my own configuration, and I unintentionally left off this disable call. It worked just fine, though, within a Restlet Component running standalone. When I recently tried to run the Component within ServerServlet (in Tomcat 6), however, I got the stack trace reported in this thread: http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2436859 Disabling AUTO_CLOSE_TARGET didn't fix it -- instead of the error the server just hangs (in standalone mode, at least). I looked hard at the stack trace above and decided to try leaving auto-close enabled and suppressing the final flush() in WriterRepresentation.write(OutputStream). This worked. I don't get the exception any more, and I *do* get the JSON content. The standalone Component doesn't require the flush, either. I can't say for sure that leaving AUTO_CLOSE_TARGET enabled and suppressing the final flush in WriterRepresentation is really the right thing to do, but it's the only combination that works for me in both servlet and standalone settings. I suppressed the flush by overriding write(OutputStream) in my JacksonRepresentation subclass, but maybe WriterRepresentation should have a setting for this, e.g.: WriterRepresentation rep = new JacksonRepresentation(...); rep.setFlushAfterWrite(false); ... And if the auto-close-enabled and no-flush-after-write combination *is* deemed the right thing to do, that could be the default for JacksonRepresentation, and you could remove the auto-close disable logic from JacksonRepresentation.createObjectMapper. --tim ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2702864
