 ## Enable Server Reflection
 
 gRPC-Java Server Reflection is implemented by
-`io.grpc.protobuf.service.ProtoReflectionService` in the `grpc-services`
+`io.grpc.protobuf.services.ProtoReflectionService` in the `grpc-services`
 package. To enable server reflection, you need to add the
 `ProtoReflectionService` to your gRPC server.
