I had a problem like this and resolved it by adding: Engine.getInstance().getRegisteredConverters().add(0, new JacksonConverter()); to my Android code before I constructed my client resource
My code is just a little tweak on the documented version at: http://wiki.restlet.org/docs_2.0/13-restlet/275-restlet/266-restlet.html Good luck!
