Jakarta Commons IO file filters

[elektrophyte]

Has anybody worked with the Jakarta Commons IO File utilities? I am
trying to get an ArrayList of Files with names that match a String. I'm
searching recursively in a directory and subdirs.

Here is my code:

Collection docs = FileUtils.listFiles(
documentDir,
FileFilterUtils.nameFileFilter(filterString),
TrueFileFilter.INSTANCE);

The Collection "docs" always winds up with nothing in it.

Any help would be greatly appreciated.

Thanks,

E

I wrote my own set of filters. You are free to use them. See
http://mindprod.com/products1.html#FILEFILTER

Consider that filters have to decide on file or directory. Perhaps
you are ignoring that part and getting everything turfed on that
account alone.

Consider that filters work with unqualified filenames, including the
dot.extension.

With my own filters, since you have source, it is pretty trivial to
add some debug code to figure out why files are being excluded. It
would become pretty obvious running the code in Eclipse tracing
through a few files what the problem is.
