Re: Exception in second inOut jms endpoint returns null body to aggregation strategy

[TonyK <ak...@sfgmembers.com>]

I've trimmed my code to the bear minimum. If I throw the exception in my
first call to the child route, then I get the body returned to my
aggregation strategy, but when I throw an exception on my second call the
body is null when I get to the aggregation strategy. Why would this be?

--------------------------------------------------------------------
Main Route
--------------------------------------------------------------------
	<camelContext xmlns="http://camel.apache.org/schema/spring"
		errorHandlerRef="defaultHandler">

		<errorHandler id="defaultHandler" type="DeadLetterChannel"
			deadLetterUri="smtp://localhost:8059?to=mrr@aaaa.com&subject=Complete" />

		<route id="REMOVETestEnvironmentWriteToQueue">
			<from uri="{{endpoint.IncomingRequest}}" />
			<to uri="jms:ANN.NB.ILLUST.BATCH" />
		</route>

		<route id="IllustrationsBatch">
			<from uri="jms:ANN.NB.ILLUST.BATCH" />
			<camel:split strategyRef="IllustAggregationStrat"
				parallelProcessing="false">
				<xpath>/TXLife/TXLifeRequest</xpath>

*If I throw an exception on the first call to the child route, then my error
handler will send me an email with the body of "Test" and when I reach my
aggregation strategy the body also says "Test". Which is what I would
expect.*
				<transform><camel:simple>Test</camel:simple></transform>
				<inOut
uri="jms:ANN.NB.ILLUST.IMAGE.IN?transferException=true&requestTimeout=120000"
/>

*If I throw an exception on the second call to the child route, then my
error handler will send me an email with the body of "Test2", but when I
reach my aggregation strategy the body is null.*
				<transform><camel:simple>Test2</camel:simple></transform>
				<inOut
uri="jms:ANN.NB.ILLUST.IMAGE.IN?transferException=true&requestTimeout=120000"
/>

			</camel:split>
		</route>

	</camelContext>

--------------------------------------------------------------------------------------
Child route
--------------------------------------------------------------------------------------
	<camelContext xmlns="http://camel.apache.org/schema/spring"

uri="jms:ANN.NB.ILLUST.IMAGE.IN?transferException=true&requestTimeout=120000"
/>
			<to uri="bean:fakeImageCall" />
		</route>

	</camelContext>

------------------------------------------------------------------------------------------------------
Bean
----------------------------------------------------------------------------------------------
public class ImageServiceCall {

	public void process(Exchange exchange) throws Exception {
		if(exchange.getIn().getBody(String.class).equals("Test2")){
			throw new IOException();
		}
	}
}
