Here it is explained that I shall always use getClass().getResourceAsStream() so that I can read from jar, network. I shall not use getClass().getResource.toURI().toString(). So I guess, I shall not use getClass().getResource.getFile() or getClass().getResource.getPath() either for the same reason.

But what if I need to use File API (Apache Commons for example). I need to get a file from my resource folder (Eclipse) as File (or String, I can make new File(String)). What shall I do? Not use Apache Commons (say FileUtils.readlines(File), FileUtils.lineIterator(File) etc...)?

And how shall I access a file from my resources folder writing code for a web app (which will be on application server as *.WAR = jar)?

Is it right. that I cannot use File API (Apache Commons FileUtils.readlines(File), etc)? Or there is a trick?

Use `IOUtils` instead? – Oliver Charlesworth Apr 25 '18 at 20:33

Perhaps it's best to explain the entirety of your problem, not just the part that you (think you) have solved. Why do you need to use the File API? – SeverityOne Apr 25 '18 at 20:34
How would you be using this file object? Can we have a code sample? – Cardinal System Apr 25 '18 at 20:56

Yes, don't use FileUtils with resources, they are not meant to be regular files. – zapl Apr 25 '18 at 20:56
