[mule-user] handling exception in xsd validation

[Davide Piazza]

Hi,
I want to validate an XML file against its XSD and in case the validation fails move that file in an error directory.

I see that exception-strategy can be use globally or at component level or at connector level.
The validation takes place in the org.mule.routing.outbound.FilteringXmlMessageSplitter router. I tried several combination of different config but my file is never routed to the error directory. I only see the excepted validation exception.

Does anybody a similar scenario working? I suppose yes because I think this is a very tipical one.
TIA

regards
Davide.

[Andrew Perepelytsya]

Have you tried to put an exception strategy on the file connector?

[Davide Piazza]

Thanks Andrew,
it worked :)
But now I would like to remove the original file from the input folder otherwise in the next poll mule would process it again.
How could I do that?

thanks
Davide.

ExceptionStrategy?

[Davide Piazza]

Yes, indeed ;)
I was just wondering if there were a config to do that without coding and subclassing DefaultExceptionStrategy.
Thanks for the help
Davide.
