What parameters do you need? If I understand you correctly, you want
to create a bean that "creates" your Message object, right? And you
need parameters to be passed in to your bean that are used to set the
order/host fields of the Message object?

Where would those values be? Camel really deals with the idea of an
Exchange.. this exchange can have properties and a message with
headers/body. If you want to bind specific parameters or headers to
your bean, you can do so with this:

Check the link i posted above. That should help. Or take a look at
Camel in Action book pp 105 and 11.

So what doesn't work?
Where/how are you invoking the route (calling the direct:start endpoint)?

I think you have that already :) the loadbalancer example does that.

If it requires parameters, you can do so w/ bean binding, or in a processor

Not sure yet :) You have to invoke the route some how....
