Using apache camel failover loadbalancer
I am new to camel and trying to use failover loadbalancer. I have list of
endpoints (say, A, B, C) which can be used to send message such that if one
fails the endpoint next in the list can be tried. lets say B was success.
After successful send, B will receive an exchange which can be used to know
the status of the message sent earlier.
I have tried various versions for loadbalancer as:
Case-1
from(fromEndpoint)
.errorHandler(defaultErrorHandler)
.loadbalance().failover()
.to(smppEndpointList)
.process(getSendProcessor);
> This fails to use the processor returned by the getSendProcessor() and
> overall the flow fails.
Now I change the above version to this.
Case-2
from(fromEndpoint)
.errorHandler(defaultErrorHandler)
.to(smppEndpointList)
.process(getSendProcessor)
.loadbalance().failover();
> Here if the smppEndpointList has only one endpoint then the call is
> successful but in case of multiple endpints in the list it fails. Also

Case-3
from(fromEndpoint)
.errorHandler(defaultErrorHandler)
.process(getSendProcessor)
.loadbalance().failover()
.to(smppEndpointList);
> This also fails as the processor returned by getSendProcessor is not used.
Can some one please suggest the correct implementation. I am stuck over this
for long.
Thanks
