HOW: Apache Camel, Regex match files

Yeah you need to use the include/exclude/filter option if you want to filter out files based on patterns. The fileName option is for a single file.

So in your case, remove fileName option and replace it with include=.*2280.xsl. Mind that the include is based on Java regular expressions, so we use dot star to indicate wildcard. More details here: https://camel.apache.org/components/latest/file-component.html. The ftp component inherits 99% of the options of the file component, so that is why I refer to the file wiki page.

Use the include option that uses Java regular expression:

include=.*2280\\.xsl

Please, mind the \\ before the dot .

Alternatively, use antInclude:

antInclude=*2280.xsl
