Re: handling exception at endpoints / solved
Hello
ok i got the error. wrong signature in my handleException method.
it should be handleException(Exchange exchange)
i think Claus might have mentioned me the correct signature in some past
email, but somehow that mail got lost
Good thing i m pleased about is that i spotted the signature error while
learning how to test routes offline :)
I m starting to love camel :)
thanks and sorry for my noise

Re: handling exception at endpoints / solved
Posted by Christian Müller <ch...@gmail.com>.
Good to know you could figure it out by yourself. I would response later to
your question with the solution you mentioned (I'm on a shopping tour with
my girl friend at present... ;-) ).
There are also others. Have a look at the parameter binding annotations:
http://camel.apache.org/parameter-binding-annotations.html
Happy Camel ride,
Christian
