I'm not sure that would work. As I stated in my original post, I don't want
to send the entire message to the error queue, just the portion that was
invalid. So, if my original message has, say, 11 readings, and 3 of them
are bad, I only want to send the 3 bad ones to the error queue. During
processing, I stick the bad readings into an "error object". It's the
contents of this object (that I can easily marshal to XML) that I want to
send to the queue.
FYI, here is a simplified version of my route:
from("jetty:http://0.0.0.0:8282/process";).convertBodyTo(String.class)
.inOnly("jms:queue:data.inbound")
.unmarshal(jaxbDf)
.beanRef("dataProcessor", "process")
