java - JAX-RS CXF access HTTP body from @BeanParam -

my question simple, didn't manage find response... possible jax-rs (using cxf implementation) access http request body @beanparam annotated parameter ?

i tried it doesn't work :

@path("/courses") @produces(mediatype.application_json) @consumes(mediatype.application_json) public class carsresource {      @post     @path("/{id}")     public course update(@beanparam carupdaterequest request){         ...     } }   public class carupdaterequest {      @pathparam("id")      private string id;      private carupdatedata data; // inject here body using jsonprovider  } 

it seems helloword example can't find working example. it's strange jax-rs doesn't have @bodyparam...
