File component - run them sequentially
Hi there,
I have a doubt.. I've got 3 File components. But I wanna know how to make
them run sequentially..in other words, the second File component will be run
just when the first one finishes its work in all the files from that
directory, and so on.! I tried to use 'delay', but it's not always i will be
able to know the exact time the first component will finish. I searched a
lot about this but i couldn't find a answer..
Thanks!

You can use the API on CamelContext to start|stop routes. So you would
need to figure out
when there is no more files on route1, to start route2, and so forth.
And what should happen when route 3 is done. Should it start route1.
So it goes in round robin?
You can enable the sendEmptyMessageWhenIdle=true, which will have an
empty message being sent out in the route.
Then you can use that to know that there is no more file, and then
start the next route
http://camel.apache.org/how-can-i-stop-a-route-from-a-route.html
In Camel 2.11 it may be a bit easier with the control bus eip
http://camel.apache.org/controlbus.html
You can also use on completion
http://camel.apache.org/oncompletion.html
That may be easier. The file consumer is batch consumer, so there is a
special header that tells when the batch is done = no more files.
Then in the on consumer you can filter on that, and react upon
stopping current route, and start next.

Each file component handles with a diferent directory..
directory "root" (File Component 1)
directory 1 (File Component 2) - File Component 1 finishes
processing all the files from its directory, so it starts
directory 2 (File Component 3) - File Component 2 finishes
processing all the files from its directory, so it starts
Whether I don't use the option 'delay'..the 3 file components starts
randomly. I tried to create a logic putting them inside a Direct
component(don't know whether it's a good practice), but they even start and
stop randomly and simultaneously.
Thanks!

Why do you have 3 file components, why not have only 1?
