问题
I am building a routing slip bean and want to apart from the dynamic routing also to send a parameter to the endpoints of the recipients list.
I wish to use something like "direct:test?param=value", where param and value are set inside the routing slip POJO
From what I understand from the direct component, a single "direct:test" endpoint will receive all the routed exchanges, however I need a way to read the param send from the routing slip
How can I use this param to the endpoint which receives the exchange? Is it a property of the exchange?

Pan,
I'd use the header functionality of camel. It's quite versatile and you can handle it using predicates for some nice DSL or spring control, or in a bean/processor by doing myExchange.getIn().getHeader("foo").
