Dynamically configuring FTP component from Exchange input msg?

I have a requirement to perform FTP operations on behalf of 100's of parties, all of which have their own FTP credentials.  Obviously, it would not be practical to configure 100's of instances of the FTP component with different user's login/password hardcoded in the URI.  I am wondering if there's a way for the FTP component to pull the user/password from the message payload or headers?

Thanks

Hi Charles, 

yes exactly in spring dsl you can refer to producer templates as follows:<camelContext xmlns="http://camel.apache.org/schema/spring">

   <template id="producer"/>

   <route>
        <from uri="activemq:queue:Endpoint.OUTGOING"/>
        <recipientList>
           <header>myHeader</header>
        </recipientList>
    </route>
</camelContext>

Consumer Templates just incase:

<consumerTemplate id="consumer"/>


There is some useful documentation here, especially for implementing strategies to deal with common issues like stopOnException:

http://camel.apache.org/recipient-list.html

Thanks

Graham

Graham,

Thanks a lot for the suggestion.  If I wanted to express this flow in Spring DSL, I assume I would need to create a custom producer template ans refer to that via a <template/> tag, yes?  

Thanks again,

Charles

Hi Charles, 

Yes this is possible, you can get the value from either the header or the body content as you prefer and then you can use the recipientlist to create the dynamic endpoint. You could use something a little like this:

Processor ftpProcesor = new Processor () {
public void process(Exchange exchange) throws Exception {
Message in = exchange.getIn();

String username = in.getHeader("FTP_USR_NM", String.class);
String password = in.getHeader("FTP_PASSWORD", String.class);

ftpEndpointURL = "ftp://" + username + "@ftpserver.ftp.com:22/Test?password="+password;
}
}

from("activemq:queue:ftp.OUTGOING)
.process(ftpProcesor)
.recipientList(ftpEndpointURL)

You could also pass all of the username/password values in at once in a comma separated list, or xml file or some other format and then loop through each pair and then perform the FTP operations as you go.

Hope this helps.

Thanks

Graham

}
}

from("activemq:queue:ftp.OUTGOING)
.process(ftpProcesor)
.recipientList(ftpEndpointURL)

You could also pass all of the username/password values in at once in a comma separated list, or xml file or some other format and then loop through each pair and then perform the FTP operations as you go.
