Need to report an error if the file does not exist

[sergevil]

I have the route that starts with:

<from uri="file:}?fileName={{input_filename}}&amp;noop=true" />

I need to report an error if the file does not exist. But in that case my route hangs on polling for a file. What parameters should I use to avoid polling?

Thank you in advance!

The only solution that I found is:

     <pollEnrich uri="file:{{input_dir}}?fileName=}&amp;noop=true" timeout="5000" />

......................

Is it one more elegant?

You can use the sendEmptyMessageWhenIdle option: http://camel.apache.org/file2
