Errai Jax-RS not firing

Question

I really dont understand why errai jax-rs is not firing:

Usage

@Inject
private Caller<ApiService> myService;

myService.call(new RemoteCallback<MyModel>() {
            @Override
            public void callback(MyModel result) {
                    t.cancel();
                    GWT.log("Response from server: " + result);
                }
            }).create(model);

Service

@Path("api")
public interface ApiService {
    @POST
    @Consumes("application/json")
    @Produces("application/json")
    public MyModel create(MyModel model);
}

public class ApiServiceResource implements ApiService {

    private final InternalService internalService;

    @Inject // Guice
    public ApiServiceResource(InternalService internalService){
        this.internalService = internalService;
    }

    @Override
    public MyModel create(MyModel model) {
        System.out.println("Creating model: " + model.toString());
        return internalService.createModel(model);
    }
}

Guice ServeModule:

@Override

     bind(ApiService.class).to(ApiServiceResource.class).in(Scopes.SINGLETON)
}

Answer 1

Errai has it's own marshaller http://docs.jboss.org/errai/3.0.0.Final/errai/reference/html_single/#sid-5931328

and in order it work properly your POJO has to be marked with @Portable annotation. Check that you have it in your MyModel class.

Without it you'll get java.lang.RuntimeException: No marshaller for type: *.MyModel
