Hello charles, >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. yes, you need both.
The core module of the GAE edition is required in the "WEB-INF/lib" directory. In addition put also the org.restlet.ext.gwt.jar (server side serialisation/deserialisation of GWT-RPC representations) The core module of the GWT edition is only useful at development time and must not be put in "WEB-INF/lib" directory. I put in a "lib" sub directory of my projects, at the same level than the "src" directory. >How can I solve these errors: No source code is available for type >org.restlet.data.Preference<T> Just make sure to import valid packages and classes in your GWT pages: the package must start with "org.restlet.client."
