FTP Component That Consumes On Demand
Hi,
Is there an ftp component that consumes a file on edemand? and not a
polling.
for example i have the file name already and want to fetch this file coming
from an ftp server,
how would i route it?
from("direct:getfile").to("ftp://someurl?file-name=sd?")
would this fetch a file or would this create a file on that server?
thanks
carlo

Right, this use case is even exactly described at

This is possible using the polling consumer EIP. It will poll for a
remote file on the FTP server.
And from the routing DSL you can use pollEnrich also.
However one caveat is that setting the endpoint uri in a dynamic
fashion is not easy. And we know this and there is a JIRA ticket for
that.
So yes its possible.

I think Carlo wants to be able to *not* always poll for new files,
which is what the polling consumer does.
Instead, he's looking for something like an HTTP GET method, which is
not really a consumer but a provider with no input.
The idea (iiuc) would be to send an exchange to the ftp provider which
would cause the retrieval of the given file.
I don't think this is possible yet.

Hi
You are looking at the polling consumer EIP
http://camel.apache.org/polling-consumer.html
However Content Enricher EIP is also doable
http://camel.apache.org/content-enricher.html
as there is a pollEnrich DSL for that. However passing in the filename
on the URI is a bit hard to do.
There is a JIRA ticket to enhance this in the future
