AppEngineのリバースプロキシ（restlet 2.1）：404 - クライアントプロトコルが見つからない

Question

AppEngineを使って、Restartをサードパーティのjson/xmlサービスのリバースプロキシとして使用しようとしています。

• AppEngineのバージョン1.5.5
• のRestletこのように私のweb.xmlのGAE版2.1RC1

IセットアップのRestlet：

<servlet> 
<servlet-name>​RestletServlet</s​ervlet-name> 
<servlet-class​>org.restlet.ext.ser​vlet.ServerServlet​</servlet-class>​ 
<init-param> 
    <param-name>or​g.restlet.applicatio​n</param-name>​ 
    <param-value>b​e.koma.server.MyAppl​ication</param-va​lue> 
</init-param> 
</servlet> 
<servlet-mapping> 
<servlet-name>​RestletServlet</s​ervlet-name> 
<url-pattern>/​api/*</url-patter​n> 
</servlet-mapping> 

私はWEBに次のjarファイルを追加しました-INF/lib、GAEバージョン2.1RC1

org.json.jar 
org.restlet.ext.crypto.jar 
org.restlet.ext.gae.jar 
org.restlet.ext.gwt.jar 
org.restlet.ext.jackson.jar 
org.restlet.ext.json.jar 
org.restlet.ext.net.jar 
org.restlet.ext.servlet.jar 
org.restlet.ext.xml.jar 
org.restlet.jar 

これはbe.koma.server.MyApplicationの実装です。

public class MyApplication extends Application { 

    @Override 
    public Restlet createInboundRoot() { 

     Router router = new Router(getContext()); 

     String target = "http://otherservice.​com/users.xml"; 
     Redirector redirector = new Redirector(getContext(), target, Redirector.MODE_SERV​ER_OUTBOUND); 
     router.setDefaultMat​chingMode(Router.MOD​E_FIRST_MATCH); 

     getConnectorService(​).getClientProtocols​().add(Protocol.HTTP​); 

     router.attachDefault​(redirector); 

     return router; 
    } 
} 

私のブラウザまたはカールからotherservice.comを呼び出すと正常に動作します。

しかし、私がRestletを呼び出すと、クライアントプロトコルが見つからないため404が返ってくるのですか？
