Hi,
I've a problem calling a REST based service with dynamic uris in combination
with a failover load balancer.
Below is how I do it at the moment but I'm open to better solutions.
It would also be great if there is a way that I can inject a dynamic number of
endpoints, so I could inject a thrid cluster node without changing the code.
I've designed the route as
from("direct:a")
.loadBalance()
.failover(-1, false, false)
.recipientList(simple(endpoints[0]))
.recipientList(simple(endpoints[1]))
.end()
Which leads to this exception:
Caused by: java.lang.ClassCastException:
org.apache.camel.model.LoadBalanceDefinition cannot be cast to
org.apache.camel.model.ExpressionNode

If I change the route to
from("direct:a")
.loadBalance()
.failover(-1, false, false)
.process(new RecipientList(getContext(), simple(endpoints[0])))
.process(new RecipientList(getContext(), simple(endpoints[1])))
.end()
It works as expected, so I guess there is an internal bug somewhere.
Thanks,
Sebastian
