Have you added the AspNetCompatability attribute to your service implementation class?

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ServiceImpl{
}

Also, change you might need to change your binding to webHttpBinding as basicHttpBinding is for SOAP rather than Json
