pollEnrich doesn't look for FILE_NAME

[Dragisa Krsmanovic <dk...@plos.org>]

I am trying to use pollEnrich to add file to message body as described
in http://camel.apache.org/content-enricher.html

Here is full example:

from("direct:start")
.setHeader(Exchange.FILE_NAME, constant("some.file"))
.pollEnrich("file:/test/data?noop=true&readLock=none",10000)
.to("file:/test/ftpdir");

For some reason, pollEnrich doesn't seem to take Exchange.FILE_NAME
header into account and fetches the first available file, not the one
specified in setHeader(...)

Is this a bug ?

I actually think you hit a shortcoming of the PollingConsumer API.
This API does not support supplying options from outside.
Could you create a JIRA ticket then we can have a look at in how to
provide such a new feature to this API.

Instead of the pollEnrich you can use a processor/bean etc. where you
use the consumer template which supports you to dynamic set the
endpoint URI.
In which this endpoint URI should  contain a fileName option which the
file you want to read.

Is there a way to set file name in pollEnrich dynamically ?

I want something like:
...
.setHeader(Exchange.FILE_NAME).xpath("...")
.pollEnrich("file:/test/data?noop=true&readLock=none", 10000)

The first argument to pollEnrich() specifies a consumer endpoint, not a
producer endpoint. So, instead of sending the current exchange (the one
containing the header) to the endpoint, the pollEnrich() command creates a
new exchange object containing one of the files from the specified
directory, /test/data. In other words, the current exchange is ignored when
pollEnrich() polls the file system, and this is the expected behaviour.

If you want to read a specific file, you could use the fileName option
option in the URI. For example:

.pollEnrich("file:/test/data?noop=true&readLock=none&fileName=foobar.xml",10000)

For details of the fileName option, see http://camel.apache.org/file2.html.
