Trying to put a file in a dead letter folder
I have the following camel context.
Every thing works fine for an XML file that is parsed correctly
However if an Exception occures it ends up in the processed folder
rather than in the dead letter folder?
Is there somthing I need to do to stop the processing amd leave the file in
the
dead letter folder ?? I would tend to think I am just missing a config?

Hi
I think you need to use <from ref="incidentFileEndpoint"/> to indicate
a REFERENCE to an endpoint instead of using uri.

Yes that is because you use doTry .. doCatch that works just as try ..
catch in regular Java. So you handle the exception locally in the
doCatch block.
So even if you route the message to your own deal letter destination
in the doCatch block Camel will afterwards think the file was
processed with success and move the file to .camel sub folder as its
done OK.
You should just remove all the doTry .. doCatch and then rely on the
Dead Letter Channel to move failed files to a dead letter destination
instead.
See more at:
http://camel.apache.org/error-handling-in-camel.html
http://camel.apache.org/dead-letter-channel.html
And this for how to configure it in spring XML that you use

Your right it should be:
<camel:from ref="incidentFileEndpoint"></camel:from>
I have changed it from ure to ref,
However when I test a poorly formed XML file the unmarshal
throws an exception but the file ends up in the .camel/
processed directory rather than the deadletter/ directory?
