Restlet - Connection Problems - 406 Not Acceptable - Plain Text - rest

Question

couldnt find somewhere else advice.
I am writing a Restlet JSE Client for a Jersey(!) Restful Service. I already wrote a Jersey client for that and it is working, so the jersey service is alright. Now I get problems in writing a restlet client:
My Service root adress is:
http://localhost:8080/com-project-core/rest, so I call:
ClientResource = service = new ClientResource("http://localhost:8080/com-project-core/rest");
My Basic Auth Credentiels are admin and xxx, so I call:
service.setChallengeResponse(ChallengeScheme.HTTP_BASIC, "admin", "xxx");
Now the problems:
ClientResource service = new ClientResource("http://localhost:8080/com-project-core/rest/ping");
calls up my service. After that I try
String myString = service.get(String.class);
System.out.println(myString);
I get a:
08.07.2012 17:41:48 org.restlet.engine.http.connector.HttpClientHelper start
INFO: Starting the default HTTP client
in my output. Not more! The Junit Test says:
Not Acceptable (406) - Not Acceptable
So he can find the resource but cannot produce #Produces("text/plain") ??
So when I remove #Produces("text/plain") on server side it works!!
For the resourcey my server side looks like this:
#Path("/ping")
#RolesAllowed({"admin", "user"})
public class ConnectedResourceBean implements ConnectedResourceIF {
#GET
#Produces("text/plain")
public String getPingMessage() throws NamingException {
return "Hello World";
}
}
For my pom in set this dependencies:
<dependency>
<groupId>org.restlet.jse</groupId>
<artifactId>org.restlet</artifactId>
<version>${restlet.version}</version>
</dependency>
<dependency>
<groupId>org.restlet.jse</groupId>
<artifactId>org.restlet.ext.xstream</artifactId>
<version>${restlet.version}</version>
</dependency>
As I said, its working with my jersey client.

Answer 1

No way: Restlet had problems with
#Produces("text/plain")
on jersey server side. Can someone explain me that fact?
Edit:
Made it work with
<properties>
<restlet.version>2.1-M3</restlet.version>
</properties>
