Hello Thierry, I do not understand your answer because I am a beginner with this technology.
I strictly followed this page to build my GWT client : http://wiki.restlet.org/docs_2.0/13-restlet/21-restlet/318-restlet/303-restlet.html#dsy303-restlet_gwt In GWT client, we can read these lines : ContactResourceProxy contactResource = GWT.create(ContactResourceProxy.class); // Set up the contact resource contactResource.getClientResource().setReference("/contacts/123"); contactResource.getClientResource().getClientInfo().getAcceptedMediaTypes().add(new Preference<MediaType>(MediaType.APPLICATION_JAVA_OBJECT_GWT)); How can I solve these errors : No source code is available for type org.restlet.data.Preference<T> and No source code is available for type org.restlet.data.MediaType I do not understand if I have to include the two files org.restlet.jar (this from GWT directory and this from GAE directory) in referenced libraries. bests regards ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2713551
