Hello Gabriel, the following error is due to the fact that, on server side, the gwt extension is not registered, certainly because it is not on the classpath (I mean the org.restlet.ext.gwt.jar file). You can put it also in the WEB-INF/lib directory.
Internal Server Error (500) - Can't parse the enclosed entity because of its media type. Expected <application/x-java- serialized-object+gwt> but was <application/x-java-serialized-object>. Make sure you have added the org.restlet.client.ext.gwt.jar file to your server. The following error is due to the fact that, on server side, the dependency of the gwt extension is not part of the classpath (I think this is gwt-servlet.jar), you can put it also in the WEB-INF/lib directory. java.lang.NoClassDefFoundError: com/google/gwt/user/server/rpc/SerializationPolicyProvider Best regards, Thierry Boileau Hello Jerome, > I've just tried it with the libraries you have provide, and it still > doesn't work :( > > My steps were: > - change the libraries on the eclipse project so I have the following: > On the Reference libraries of the eclipse: > -org.restlet.jar (from jee) > -org.restlet.ext.gwt.jar (from jee) > -org.restlet.ext.servlet.jar (from jee) > -org.restlet.jar (from gwt) > -RestTestServer.jar (compiled from the Netbeans project, to allow the > use of the Contact object) > > On the war/WEB-INF > -org.restlet.jar (from gwt) > -org.restlet.gwt.jar (from jee) > -org.restlet.ext.servlet.jar (from jee) > > -Changed the libraries on the netbeans project (the one which runs the > restlet rest server) > In this project I have had to remove the use of the simple framework (as > it is not available on the jee edition) and run it with the embebed restlet > server. > So the libraries that I have now on the netbeans is just the > org.restlet.jar (from the jee edition) > > If I start the netbeans server and then the eclipse web app. When I try to > retrieve the contact resource from the client (/contacts/123) I receive the > following error on the eclipse: > > Información: Redirecting via client dispatcher to: > http://localhost:8112/contacts/123 > mar 22, 2012 9:00:37 PM org.restlet.engine.log.LogFilter afterHandle > Información: 2012-03-22 21:00:37 127.0.0.1 - /127.0.0.1 > 8112 GET /contacts/123 - 200 - 0 79 > http://127.0.0.1:8888 Mozilla/5.0 (X11; Linux x86_64) > AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.79 Safari/535.11 > http://127.0.0.1:8888/TestGWTRestlet.html?gwt.codesvr=127.0.0.1:9997 > > Internal Server Error (500) - Can't parse the enclosed entity because of > its media type.
