Thank you, Claus, for this important caution but we didn't notice this in Camel
documentation.
We are newly developing our projects with Camel, and it is important for us to
use most promising ways.
Which DSL is most valuable for future use cases?
Is there any roadmap for Camel? I found some old roadmaps.
My other question is about your DLQ route suggestion.
We found a way for logging in errorHandler by using onPrepareFailureRef
attribute.
Which way is good a new DLQ route or onPrepareFailureRef?
Thanks again,
Burcu

Hi
Just a caution that using camel-spring-xml with Spring XML is becoming
legacy/deprecated.
It is the very old XML DSL in Camel v1/v2.
So what you can do is to use a route as DLQ that uses direct where you can then
do
from direct myDLQ
log bla blah
to jms:dead
And then configure the error handler to use direct myDLQ
Then you can do anything you like in the route
