Sorry for resurrecting this old thread, but I was wondering if you found a better solution than: Engine.getInstance().getRegisteredConverters().clear();
My post(someObj) were working fine - being handled by the @Post("json") method in the interface (using Restlet 2.2 GAE edition on the server, Restlet 2.2 Android on the client). Then for Android reasons I had to change SomeObj to implement Serializable. This seemed to change the media type to application/x-java-serialized-object which caused my post(someObj) to return a 415 error. Clearing the converters fixed the problem, but I was just curious if you found a better solution. Thanks!
