-------------------------------------

Hello Chris
thank you for your reply... just to clarify, if I throw an ODataApplication exception in the producer code, will the consumer receive an status code of 500 with the message I entered in the exception? How should we deal with other status codes like 404, etc?

Regards
Michele

> Hello,
> we have an OData 2 service which currently only supports GET requests. We are investigating what is required to extend the service to support POST, PUT and DELETE.
> Looking at your documentation, it appears that we can use the the writeEntry() and writeFeed() methods of the EntityProvider class to perform the required operations. These methods return an ODataResponse. Can we use the ODataResponse to provide error messages to the clients in case the POST/PUT operations can't be completed successfully?
> Delete operations are quite different as clients simply need to use the DELETE method against an entry URL to delete it. In these cases how can we handle error conditions? What error code should we return when an entry can't be deleted and how can we tell the client the reason for the failure?
> Finally, we would like to enforce that client invoking POST, PUT, DELETE operations provide an audit message... How can we achieve this? Do we need to get the clients to POST the audit message first and the reference it in the other operations?
> Thank you for the information
