Dead Letter Channel /Error Handling / Logs

[Hervé BARRAULT]

Hi,
I defined a simple route with camel-cxf :

from("cxf:bean:myCXFEndpoint")
            .process(preProcessor_)

When having an exception I have two logs (one from camel one from cxf).

Now, i want to add an exception handling (to avoid the camel log and do
some processing for the exception).

for example :
from("cxf:bean:myCXFEndpoint")
            .errorHandler(deadLetterChannel("seda:deadLetterEndpoint"))
            .process(preProcessor_)

But in this case, I loose the exception (behavior of a deadletterChannel).

So I have tried something like this :
onException(Exception.class)
        .handled(false)
        .to("seda:deadLetterEndpoint");

from("cxf:bean:myCXFEndpoint")
        .process(preProcessor_)

But in this case, I have also the log of the default Error Handler

Should I implement completely an error handler to have this behavior (
processing an error without marking it as handled and without an ERROR log)
?

FYI : I'm using an old camel 2.4

Thanks for answers
