Content enrichment is a very generic pattern and the default one
provided by servicemix-eip uses a very simple scheme which is to
aggregate the original request and the response from the service
called into a single message by concatenating them.
If it does not suit your needs, as it seems to be the case, you should
define your own aggregation strategy. You can do that by extending
the ContentEnricher class and overriding the needed methods.
Actually, the ContentEnricher should be split into two classes, one
would be AbstractContentEnricher that provides the JBI exchange
processing and the current one would inherit the
AbstractContentEnricher to provide the default and simple behavior
(feel free to submit a patch for this if you want). Btw, another
enhancement for the ContentEnricher class would be to support sending
exchanges asynchronously.
Anyway, as the current class is not really extensible, you'd have to
copy it, modify the enrichment logic and deploy it using the spring
syntax instead of using the eip namespace:
<beans>
<bean id="myEnricherEndpoint" class="youclass">
<property name="service" value="uri:service" />
<property name="endpoint" value="endpoint" />
...
</bean>
</beans>
