how can I do this?
Hello,
I have a route that takes a file from one location and processes it to
another. On Exception, I would like to have the file deposited in a
deadletter location (note, a location, not a queue). So I have that feature
working, but additionally, I would like to retrieve the exception from the
exchange, and create a log file next to the file in the dead letter
location, something like,
Demo1.ai
Demo1.ai.error.log
There does not seem to be any way to intercept the dead letter processing
just before or after moving to the dead letter queue in order to create the
log file. I can think of other ways of doing this, but I like the retry
feature of the deadletter channel, and just want to add some processing to
the end.
Thanks,
Carl

Thanks, fyi this is how I implemented in spring:
<errorHandler id = "aiErrorHandler" type="DeadLetterChannel" deadLetterUri="direct:myDLC" useOriginalMessage="true"/>
<route errorHandlerRef="aiErrorHandler">
...
</route>
<route>
<from uri="direct:myDLC"/>
<process ref="myDeadLetterChannel" />
<to uri="file://c:/tmp/data/failed"/>
</route>
Carl

Hi
You can use a direct endpoint as the DLC
errorHandler(deadLetterChannel("direct:myDLC"));
And then a route where you write the error file, and then afterwards
the original file.
from(file:inbox?delete=true)
....
from("direct:myDLC")
.bean(new WriteErrorFileBean());
.to("file:error");
public class WriteErroBean {
public void writeErrorReport(File file, Exception cause,
CamelContext context) {
... write a error file based on the error message
.. you can use a camel producer template to save the file, but of
course use Java File API also works
}
}
