Re: How to retain exchange headers through RoutingSlip

[David Hoffer]

We add the headers where we create and/or call process on the routing
slip...

exchange.getIn().setHeader("customHeader1", somedata1);
exchange.getIn().setHeader("customHeader2", somedata2);
exchange.getIn().setHeader(routingSlipHeaderName, toUris);
routingSlip.process(exchange);

But then when when the message is handled by a processor bean we try to get
the header back via

String data1 = (String) exchange.getIn().getHeader("customHeader1");

This always returns null and it removed the 'routingSlipHeaderName' header
too that used used by the routing slip.  (Its okay that it removed this
one...but need the others.)

Here is the XML config for the receiving route.  The CopyFileProcessor is
the one that does not get the custom headers.

<bean id="backupProcessor"
class="com.issinc.jms.gangplank.impl.CopyFileProcessor">
    <property name="path" value="${gp.camel.backup.dir}"/>
</bean>

<routeContext id="backup-endpoint"
xmlns="http://camel.apache.org/schema/spring";>
    <route id="to_backup" autoStartup="{{gp.camel.backup.isConfigured}}">
        <from 
uri="file://{{gangplank.data}}/toBackup/?delete=true&amp;moveFailed=.error&amp;filter=#partialFilter&amp;delay=200"/>
        <process ref="backupProcessor" />
        <onException redeliveryPolicyRef="redeliveryProfile">
            <exception>java.lang.Exception</exception>
            <handled>
                <constant>false</constant>
            </handled>
        </onException>
    </route>
</routeContext>
