Hi

Just for a poor answer check this thread:
http://www.nabble.com/ErrorHandler-%2B-DeadLetter-td19776054s22882.html

However no so elegant when you are doing the try .. catch yourself. But then 
for sure you are in control.

See isFailureHandlded in the DeadLetterChannel, however it's not a public API. 

But I guess there should be somekind of API for this and/or customization of 
the DeadLetterChannel to be configured to set/not set the original caused 
exception. As your point our that its okay you handed the exception so the 
route should continue, without indicating the exception.

Currently the DLC restores the original exception:
restoreExceptionOnExchange(exchange);

And this is the one we should configure.

Can you provide a small unit test demonstrating this, then we can use this as a 
base for the improvement in camel. Please feel free to create a JIRA ticket for 
it and attach your source there.




Med venlig hilsen

Hi,

is there a way to signal the dead letter handler that an error has been
processed by a custom processor?

We have a route like this:

exception(SomeException.class).beanRef("SomeProcessor");
from("jms:queue...").beanRef("OtherProcessor");

When there is an exception in 'OtherProcessor' the dead channel is
triggered to handle the error or redeliver it. Our 'SomeProcessor' bean
is called then and does some error handling and setting the exchanges
exception to null.
Afterwards the jms EndpointMessageListener throws an exception and does
not write back our out-Message to the reply-to queue. But we need to
send a response back even in case of an exception. Is there a way to do so?

Thanks for any help
Markus Wolf
