Thanks Mantas.
I tried it out, my route is ..
<!-- define Jackson data format -->
<dataFormats>
<json id="jackson" library="Jackson" />
</dataFormats>
<route id="isp.routes.system.deployment">
..
<setBody><constant>{"lastName": "Doo"}</constant></setBody>
<log message="json: ${in.body}" />
<!-- unmarshal JSON to Java Map -->
<unmarshal><custom ref="jackson"/></unmarshal>
<to uri="activemq:queue:IN" />
<log message="map: ${in.body}" />
<!-- process the velocity template -->
<to uri="velocity:file:{{karaf.etc}}/file.vm?contentCache=false" />
My Velocity template is ..
name=${lastName}
But I'm still missing the glue between the Java Map and the reference within
the Velocity template. Tried something but nothing was successful yet.
Any hints are appreciated.
Best
