I'm trying to use the aggregator like so:
<route id="BundlingRoute" autoStartup="true">
<from
uri="file:{{directory.outgoing}}?include=\A{{edifact.messagePrefix}}.*" />
<to uri="xslt:file:{{schema.edifactToIntermediate}}" />
<setHeader headerName="virNo">
<xpath>
/edi/transaction[1]/@VirNo
</xpath>
</setHeader>
<unmarshal ref="jaxbIntermediate" />
<aggregate strategyRef="EdifactAggregator"
completionFromBatchConsumer="true">
<correlationExpression>
<header>virNo</header>
</correlationExpression>
<marshal ref="jaxbIntermediate" />
<to uri="xslt:file:{{schema.intermediateToEdifact}}" />
<to uri="file:data/out/outbox/vans_sim" />
</aggregate>
</route>
This works fine, aggregation etc. works, until I reach the last file of the
directory I get an exception:
This causes a loop where the file rolls back and camel reads it and rolls
back etc.
This only happens if the last file in the directory is not in a series that
will be aggregated.
so if I have:
fileA1
fileA2
fileB1
fileC1
fileC2
This works as intended. I get 3 aggregated files on the other end: fileA1,
fileB1, fileC1.
But if I do:
fileA1
fileA2
fileC1
fileC2
fileZ1
This fails and I get fileA1, fileC1 outputted. FileZ1 is getting rolled back
and throws the below exception:
[t/outbox?include=%5CAOPSIGE_.*] GenericFileOnCompletion WARN
