Claus and others:
I think I encountered a bug in using Remote File Component (SFTP) with
recipientList
My route is similar to this:
<route errorHandlerRef="dataPushErrorHandler">
<from ref="routerDeliveryChannelCQueue" />
<process ref="securityHeaderGenerator" />
<to ref="routerLogDefault" />
<recipientList>
<xpath resultType="java.lang.String">$routerRoute</xpath>
</recipientList>
<to uri="bean:responseVerificationProcessor?method=process" />
</route>
So if you look at it I send the exchange to the recipient specified in
header routerRoute. Now the recipient list uses a ProducerCache which relies
on the Endpoint URI as the key - so every time recipientList asks for a
producer, ProducerCache gives a producer from the Map based on Endpoint URI:
[code]
public synchronized Producer<E> getProducer(Endpoint<E> endpoint) {
String key = endpoint.getEndpointUri();
Producer<E> answer = producers.get(key);
if (answer == null) {
try {
answer = endpoint.createProducer();
answer.start();
} catch (Exception e) {
throw new FailedToCreateProducerException(endpoint, e);
}
producers.put(key, answer);
}
return answer;
}
[/code]
Now the RemoteFileEndpoint substitutes the uri trimmed to the "?". Hence for
"sftp://myhost:22/mydir?password=secret";, the uri is sftp://myhost:22/mydir
So essentially, even if I put a new url (with changes after the '?' -
example a change in password), still the old producer will be used by the
RecipientList unless the whole Camel is restarted (and thus clearing the Map
in the ProducerCache). I really have to do something to fix this since if a
customer corrects the password (using a separate web UI) that never gets
refreshed because the new password passed through the routerRoute header is
ignored by the recipientList due to the presence of a stale misconfigured
Producer with the "same uri" in the ProducerCache.
Claus, How can I resolve this? Could you understand what I am talking about?
Is there any work around? The latest Camel trunk does not have the Producers
-- so there is a re-engineering happening to the Producers? According to me
instead of using the pruned URI probably the full URI is to be used. Any
comments?
