The Camel file component adds a number of headers with file information. If you look at those headers there may be a file name only, file path only etc. And if you want the parent dir name only, maybe you need to work with some regular expression magic, or use some of the expression languages like groovy where you can do more powerful stuff. And as always you can bit the bullet and implement a little java method that extracts the path you need. And call this method from the spring xml. > > > -- > View this message in context: > http://camel.465427.n5.nabble.com/Get-last-file-folder-in-header-tp5728048.html > Sent from the Camel - Users mailing list archive at Nabble.com. -- Claus Ibsen ----------------- Red Hat, Inc.
