Hi
BTW its also possible to use predicates without it being a parameter
to the when DSL.
However then its a bit limited what you can do as you cannot invoke
sub methods as the Java compiler will get confused, as you cannot
"step back" into the route DSL mode, so to speak.
However in some cases that is fine if you for instance is doing a
xpath predicate that just needs a single parameter with the xpath
itself.
when().xpath("/orders/item = 'Mac'").to("jms:queue:mac")
This allows you to leverage code competion a bit more as you can press
ctrl + space after: when().
and find the possible combinations you can do.
