Resequencing with Camel
Hi there,
I'm having some trouble resequencing some queues with camel, but it's not working and I'm stumped as to why. Camel will happily route messages between queues, but the resequencer just doesn't seem to want to go.
Here is the configuration I have for camel:
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route autoStartup="true">
<from uri="activemq:queue:AnalysisIn" />
<resequencer>
<simple>in.header.JMSpriority</simple>
<to uri="activemq:queue:AnalysisOut" />
<batch-config batchSize="20" batchTimeout="4000" />
</resequencer>
</route>
</camelContext>
Can anyone shed any light on why this might not be working? I'm at a bit of a loss. I'm sure its something simple, but I just can't see it.
Thanks,
Andrew

Also - the trick with camel is when things are not doing as you want,
turn on tracer...

you may have more luck with a useful reply on the camel users forum.
One thought, are you sure the header property is present?. Could it be
"in.header.JMSPriority" (with a capital 'P')? Possibly try using a property
that you explicitly set on the original message, just the be sure the naming
and referencing is correct?
