how to use custom error handler with camel rest dsl? - apache-camel

Question

I am trying to use my own complex error handler for a rest dsl route. With myErrorHandler I define my own handler and its works. If occur an exception my handler is called and do his stuff. At the end of the handler I clear my exchange:
private void clearExchange() {
exchange.getIn().reset();
exchange.setException(null);
exchange.getMessage().setHeader(Exchange.HTTP_RESPONSE_CODE, 500);
exchange.getIn().setBody("Server Error");
}
but my main problem is, I don’t get as client a response with status code 500. My Application show me the exception stacktrace. If I use simple onException in my camelcontext, its works but my error handler are not called. I thought if an exception occur, the exchange go to my error handler and after this he go back to the consumer.
