Getting consumer endpoint details or exchange headers in custom
ExceptionHandler
Hi,
I am implementing the ExceptionHandler to catch exceptions that happen while
fetching a file remotely via FTP (e.g. IOExceptions etc.).
In my custom ExceptionHandler I need a way to figure out which endpoint/FTP
URI failed since I have more than one.
The ExceptionHandler method -handleException which gets invoked only gets
the exception and not the originating FTP endpoint. How can I possibly find
that out. I have an exchange header but I guess the exchange is not even
constructed if the first endpoint fails.
The Exception handler is an Stateless session bean and will be shared across
several routes.
I am using 2.9 release.
Thanks in advace,
-v-

Thanks for your replies.
I am indeed using consumer.exceptionHandler however when I configure an FTP
endpoint to FTP to a non-existing FTP server my exception handler is never
fired. Is it because I have to add an additional PollingConsumerPollStrategy
to handle such kind of exceptions?
I am not sure which exceptions will be thrown during prepollcheck and during
actual fetching of the file and will the exception handler not be invoked
for exceptions that get thrown during pre-poll check?

Hi
During routing a message you can use the Camel error handling.
http://camel.apache.org/error-handling-in-camel.html
Such as an onException to deal with the exception. The exchange gets
enriched with a header/property with the last endpoint it was sent to,
so you can grab that detail to known which ftp endpoint failed, you
tried to send the message to.

I'm not sure if you are using consumer.exceptionHandler[1] to do this kind of job.
There are some enhancement since Camel 2.10.0, you can define a consumer.bridgeErrorHandler[2] to catch the exception if it is thrown from the file of ftp consumer.

I have logged a ticket to improve the ExceptionHandler in a future Camel release
https://issues.apache.org/jira/browse/CAMEL-5587
