In the Processor you define the access path during "runtime": you have one exchange as input.
In the RouteBuilder you define the access path during "design time": what is to do for _every_ incoming exchange (and some may not have a hashmap as body...). But i am sure that you could use simple language for achieving your goal ... https://camel.apache.org/simple.html Maybe: setHeader("uid").simple("${body[user_name]}") Jan > -----Ursprüngliche Nachricht----- > Von: Glattfelder, Beat [mailto:beat.glattfel...@credit-suisse.com] > Gesendet: Montag, 26.
