Hi guys,

This is very good suggestion, James. To make it a little more concrete:
from(...).
unmarshal().json(JsonLibrary.Gson, Map.class).
choice().
when().simple("${body[invoices][latest][netValue] > 1000}").to(...).
otherwise().to(...).
endChoice();
You can use JSON data format [1] (I use Google GSON in the example) to
deserialize incoming message. In the example below I deserialize it to
Map, because I don't know the type of the message (to make things
little more tricky). And yeah, GSON handles nested Maps pretty well.
To analyse content of the nested maps structure you might use Simple
[2] expression (as James suggested) because it supports nested map
keys notation (as in the example). And nested maps keys is something
similar to JsonPath you wanted to have :) .
Cheers.
