MultipleResourceItemReader variation

[batchman]

I have next situation:

A number of servers produce every day some output-files. The files on each server have the same name. In each file, the first record indicates the date. When a server was not available, there is no output-file for that date, but the previous output-file is still there.

In a batch job, I want to process all these files on every server which have as first record the current date.

Can someone give me a hint on how I can implement this?

[batchman]

Can I use an MultiResourceItemReader where a Bean that returns the files on each server will be injected as a Resources-property.

The Bean that injects the resources will look for the files and also checks the first record if it maches current date.

Is this the good approach?

The problem I still have:
If I want to write the lines from the files to a db where one of the columns is the name of the server, how can I obtain the name of the server.
In other words: Is there a way in the ItemWriter to find from which resource a line is read in the MultiResourceItemReader.
