WDTypeNotFoundException: Failed to load client to connect to SLD

Hi,

I'm using Sneak Preview2 and I implement the Flight Tutorial. But I'm getting the following Exeption:

-

WDTypeNotFoundException: type extern:com.sap.test.flights.model.types.FlightsModel:com.sap.test.flights.model.types.Bapisfldst could not be loaded: com.sap.dictionary.runtime.DdException: TypeBroker failed to access SLD: Error while obtaining JCO connection: com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to load client to connect to SLD. Please check your SLD connection settings using the Visual Admin.

-

In the visual admin there is of course no SLD configured in the SLD Data Supplier Service.

Is this a prerequisite to get Adaptive RFC Models running???

Thanks

Stefan
