Path in file component using property value

[Paul Anderson <pb...@gmualumni.org>]

I have a camel-context.xml file with a route that polls a directory.  I have
a property file that is being read and I would like to use a property from
it to set the directory.  First I tried this:

<from
uri="file://${PreOutDir}?delete=true&amp;include=..*\.info&amp;maxMessagesPerPoll=1&amp;sortBy=file:name"/>

where PreOutDir is my property name but I got a message saying

Dynamic expressions with ${ } placeholders is not allowed. Use the fileName
option to set the dynamic expression.

I tried this

<from
uri="file://?fileName=${PreOutDir}&amp;delete=true&amp;maxMessagesPerPoll=1&amp;include=..*\.info&amp;sortBy=file:name"/>

but that produced
Unknown function: PreOutDir at location 0
${PreOutDir}
*

This must be possible but the syntax is not clear...

I'm using Camel 2.10.1

Does anyone know a way?

Thanks!
