Yeah if its all just file based then that may be easier. There is a done file support out of the box with Camel. http://camel.apache.org/file2 > In a related question, if my "from" were to read from a message queue but > the job itself needs to consume a file, how do I actually read an arbitrary > file in the middle of the route? I've managed to do this using <pollEnrich > uri="file: ..."/> before, is this the correct way to do this? > This is more tricky as pollEnrich requires you to either know the name to pickup, or it will pick the 1st message. And it only pickup 1 file. Its IMHO better with the done filename.
