Join two messages from two sources in zip archive.
I have a message (text file) routed in one direction a that among other
things holds an id. Then I have a bunch of text files in a directory, also
with id's. I want to match the message with the text file that holds the
corresponding id. I want to put those two files in a zip archive and store
them in a directory.
I'm thinking about using an aggregator or pollEnrich with a custom
AggregationStrategy that takes a batch of 2, and checks whether the input
has already been zipped, if yes then open ziparchive and add new entry, if
not then create zip archive and add entry.
The problem seems similar to Listing 3.3 in Camel In Action but how do I
select with pollEnrich that I only want to consume one particular file
depending on the id inside and leave the rest?

Yeah deleting the file is fine, as you are handling all the file stuff yourself.

Yeah that works. I would like to consume the file also, right now I'm just
deleting it after I've gotten what I want from it. Is there a better
solution?

There is one limitation with pollEnrich, which is that it does not
support if the route is started from a file endpoint.
That kinda currently conflicts with the current codebase. There is a
JIRA ticket to enhance this in the future.
If you want to grab a file, then I suggest to use a Processor which
can easy do it like this
.process(new Processor()) {
public void process(Exchange exchange) throws Exception {
String filename = .... // you compute the file name to poll
File file = new File(filename);
// use the Camel type converters to load the file and return its
content as a String
String fileBody =
exchange.getContext().getTypeConverter().convertTo(String.class,
file);
// now you can merge that file body with the existing message on
Exchange.getIn().getBody
}
}.to("your route continues here")
