Dynamic "from" and pollEnrich
I have a route with files (filename_YYYYMMDD.txt) as input endpoint i.e.
from("file://folder/filename_*.txt")
.transacted()
.id("MyRoute")
.process(new MyProcessor);
I want to trigger this route from a restful where the date part of the file
is specified in input i.e.
template.sendBodyAndHeaders("direct:myRoute", null, "header:date",
"20170508")
so I've thought I could modify my route so that the input endpoint is
dynamic by using pollEnrich i.e.
from("direct:myRoute")
.transacted()
.id("MyRoute")
.pollEnrich().simple("file://folder/filename_${header:date}.txt")
.process(new MyProcessor());
But nothing happens :(
If I had a timeout to pollEnrich then it waits for the milliseconds I
specified and then it runs MyProcessor regardless of the fact that the file
exists or not.
What am I doing wrong?
Thank you!

And you are sure the file exist at that location with that name? I have
done pollEnrich with file before and that has worked.
Can you log the headers before the poll enrich and post it?

Thanks souciance,
yes I have header where I store the date, as per my original post:
"I want to trigger this route from a restful where the date part of the file
is specified in input i.e.
template.sendBodyAndHeaders("direct:myRoute", null, "header:date",
"20170508")
"
I've tried ${headers.date} as well as ${header.date} as well as
${in.header.date} as well as ${in.headers.date}... no luck.

One question,
Do you have a header where you store the date and you want to use that, or
do you want to access the simple language to access current date?
If I am not misstaken if it is the former, it should be ${headers.date} and
for the latter it should be ${date:now:yyyyMMdd} to include year, month and
date.

Thank you Claus,
if I understood right then my route should change like this:
from("direct:myRoute")
.transacted()
.id("MyRoute")
.pollEnrich().simple("file://folder?fileName=filename_${header:date}.txt")
.process(new MyProcessor())
But nothing changed really.

The file component is configured with the directory, and then you use
fileName=xxx to specify the file name. So separate these two.
