Hi,
I'm getting exceptions when polling and processing files (in the same
filesystem). The last camel step is moving the file into a backup or into an
error directory using the parameters 'move' and 'moveFailed' of the file
component.
I'm aware of renaming problems if there's a different filesystem or
concurrent consumers trying to read the file, but I'm worried that this
happens under relatively simple circumstances (Java 6, Camel 2.8.1). Do I
have to use Java 7 for better native filesystem locking behavior ? Or can I
configure several retries ?
This is the exception that occurs - thanks for any recommendation in advance
!
