WCF Data Services access issues - 403 forbidden?

I have Silverlight 4.0 client calling WCF data service, in the ser开发者_如何学Cvice I have write allow to all (I know that is not very wise, but I want to test it first):

public static void InitializeService(DataServiceConfiguration config)
{
  // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
  // Examples:
  config.SetEntitySetAccessRule("*", EntitySetRights.All);
  config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
  config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
  config.UseVerboseErrors = true;

}

when I call the service from the client using BeginSaveChanges like this:

MyServiceEntity.BeginSaveChanges(SaveChangesOptions.Batch, OnChangesSaved, MyServiceEntity);

I receive forbidden error:

--batchresponse_a7bc1f95-8f8d-4e3b-9e24-108743499c3a

--batchresponse_a7bc1f95-8f8d-4e3b-9e24-108743499c3a--

And Batch operation response code is 202, whatever this is supposed to mean.

Any help is appreciated.

I know its seems very obvious but, did you publish your service to production after you changed the right to allow write? just make sure you are pointing to the correct service url. regards.
