Can transaction management handle FTP Rollback

ask4ralph_rokochu Nov 18, 2011 10:26 AM

Hi everyone,

Im trying to implement a rollback on an ftp file pick-up that begins a route.

I have two routes;

The first picks up a file from an ftp site and routes to a queue. The second route routes from the queue to a SOAP provider endpoint that calls a web-service.

If the web-service call fails, how do I roll-back the file pickup or create a new file with the original message?

Thanks in advance.

If you do skip the intermediate queue, and do

Then if any error calling the soap, the FTP can "rollback".

If you use a queue in between, then the FTP will "commit" if the message can safely be sent to the queue.

Thanks.

Unfortunately the message has to pass through the queue.
I ended up using a manual roll-back strategy by setting noop=true and deleting the file with a processor- using the "CamelFileName" if the soap request is successful.

Yeah good idea, as that would be your choice then.

You can also use onCompletion and filter it to trigger on failure only

The Camel in Action book, chapter 9, section 9.5 has more details about this as well.
