hi Thierry I have done the test suggested by you.Im using Restlet 1.1.8.Also i have downloaded (version 2 milestone 7 but i was not able to find com.noelios.restlet.jar inside lib folder. So i havent tried anything with this release).
The log from the Matlab Command Window is as follows: Diagnostics START Executing : com.noelios.restlet.Engine engine = (com.noelios.restlet.Engine) org.restlet.util.Engine.getInstance();.And the Output Is: Executing : System.out.println( engine: + engine);.And the Output Is: Engine : com.noelios.restlet.eng...@ae43b8 Executing : System.out.println( client connectors: + engine.getRegisteredClients());.And the Output Is: client Connectors : [com.noelios.restlet.ext.net.httpclienthel...@54919e, com.noelios.restlet.http.streamclienthel...@2437ef, com.noelios.restlet.local.clapclienthel...@1d46259, com.noelios.restlet.local.fileclienthel...@84fa6a] Executing : Client client = new Client(Protocol.HTTP);.And the Output Is: 22.02.2010 18:52:44 com.noelios.restlet.Engine createHelper WARNUNG: No available client connector supports the required protocols: 'PROTOCOL.HTTP' .
