What happens to Exchange's exception in DeadLetterChannel?
Hi there,
I'm using a Dead Letter Channel error handler and am a little confused
about what happens to the original Exception while on the dead letter
queue.
- Camel In Action says that it's stored in the
'Exchange.CAUSED_EXCEPTION' property, which doesn't seem to exist
(p127).
- DeadLetterChannel wiki page[1] says it's cleared and unavailable.
- Experimentally, it seems stored in the 'Exchange.EXCEPTION_CAUGHT' property.
Am I right about the actual behavior? If so, the Wiki should be
updated which I would be glad to try.
Thanks in advance,
David

Hi Ramon
Thanks for reporting. Somehow that errata on page 127 got removed in a
later updated. I have sent a new errate to Manning for them to publish
on the web site, which includes the errata for page 127 again.

Thanks for the hint with ICLA. I always wondered, why I cannot edit
documentation to improve it... Actually, I did not make a lot of research
:-)
I will send in a ICLA to Apache to contribute and improve documentation,
too.
Best regards,
Kai

Thanks I have updated both pages.
You are welcome to send in an ICLA to Apache, so you in the future
will be able to edit the documentation, and contribute to the project.
Its also one step closer to be a committer, as all committers must
have a signed ICLA at Apache.

Hi Claus,
Thanks for the response. It seems like it will be a while before I can
edit the wiki, so maybe someone else should do it.
I also suggest that the Log Component page[2] be updated to clarify
that 'showCaughtException' reads this property.
Thanks again,
David

That is a mistake. I will add an errata. p147 has the correct properties.

Yes its in that EXCEPTION_CAUGHT property.
For editing the wiki you can read here about that, as you need to have
karma to do that
