I'm trying to use ribbon load balancer in *Karaf* like this:
{code:java}
from("timer:consumerTimer?fixedRate=true&delay=0&period=10000")
.routeId("consumeService")
.setBody(simple("Hello, Producer! This is message from consumer
on ${camelId}/${routeId}"))
.serviceCall()
.name("producer")

.convertBodyTo(String.class)
.log("Producer response: ${body}");
{code}
