UPDATE:
As i say, the server receive JacksonRepresentation. So i need conver it to
java object.
I do this so:
-----------
public class AuthenticationServerResource extends ServerResource implements
AuthenticationResource {
@Post
public String login (JacksonRepresentation<Authentication> auth) throws
IOException {
Representation represent = auth;
//represent.write(System.out);
JacksonRepresentation<Authentication> authRep = new
JacksonRepresentation<Authentication> (represent, Authentication.class);
Authentication authObj = authRep.getObject();
auth.write(System.out);
return authObj.getLogin();
}
}
---------------
But compiler generates this error:
/******************
