Hello, I think that this error happens when the server sends an entity having a content-type different from the gwt serialized type. In order to give the ability to convert object to such representation, you must include the gwt server side extension (org.restlet.ext.gwt.2.0.4.jar) and its dependencies (should be something like gwt-servlet.jar).
Just a few explanation : the gwt client and server exchanges representations based on a serialization format developped by google team.
