status from backend for upload from backend

Hi! I am creating a syncnBo instance on the client.It is updated with the backend when I call the synchronizeWithBackend() method. Now I need to get a confirmation from the backend.Whether the data is successfully uploaded or not.So that I can display it on the client JSP page. Where can we get the status of the data upload from the client.

I have implemented the messageReplyObserver interface.

and try to see if am getting the MessageReplyType.SUCCESS.Is this the correct approach?

Even the status MessageReplyType is returned in the next synchronization.

So Could you please suggest me the correct approach for checking the for uploading the syncbo instance

Thanks in Advance,
