Well here is the documentation: http://camel.apache.org/ftp.html
(1) Add the maven dependency to your project

Thanks for pointing me to the docs but I already know them.
I also own a copy of Camel in Action.

Maybe I don't explain myself clearly, I apologise for that.

What I was doing in the first place was actually working fine : I just 
asked if it could be less ugly and if I could get rid of the consumer 
and producer templates easily.

Now I've configured my endpoints, or at least one of them, with Spring 
DSL like this :

    <camel:camelContext xmlns="http://camel.apache.org/schema/spring";>
        <endpoint id="ftpIn"

uri="ftp://${user}@${hostname}:${port}/${inputDir}?password=${password}&amp;fileName=$simple{header.CamelFileNameOnly}"/>
        <route>
            <from uri="file:src/data?noop=true"/>
            <to uri="ref:ftpIn"/>
            <delay>
                <constant>10000</constant>
            </delay>
        </route>
    </camel:camelContext>

It's working fine.

But now I'm facing another challenge I hadn't when using Camel's 
consumer template : I need to fetch the transformed file from FTP again, 
but in another directory. Clearly I need to pass the filename in the 
URI. But then the component needs to be in the same route as in this 
INCORRECT example :

        <endpoint id="ftpSender"

uri="ftp://${user}@${hostname}:${port}/${inputDir}?password=${password}&amp;fileName=$simple{header.CamelFileNameOnly}"/>

        <endpoint id="ftpReceiver"

uri="ftp://${user}@${hostname}:${port}/${inputDir}?password=${password}&amp;deleteAfter=false&amp;fileName=$simple{header.CamelFileNameOnly}"/>

        <route>
            <from uri="file:src/data?noop=true"/>
            <to uri="ref:ftpSender"/>
            <delay>
                <constant>10000</constant>
            </delay>
            <from uri="ref:ftpReceiver"/>
            <log message="End route"/>
        </route>


In my first attempt, with ConsumerTemplate, it was easy, I simply used 
the beans() element of the route and did my job by calling ConsumerTemplate.

But how do I do it without beans() ?
I could use another route but then how would I pass the file name to 
this new route ?

I must admit, as you can see, that I'm completely confused.

I hope it is clearer.
