How to avoid FileNotFound exception when running Java on Linux because of case sensitiveness?

Question

My web application runs on Windows. I would like to run my app on Linux also. I seem to have overcome most of the problems such as path separator, etc.

Real problem now is I get FileNotFoundException when the Java code tries to open a file say Abc.txt when only abc.txt exists. :(

I can't go on changing all the filenames to lowercase or uppercase as i have a whole lot of files. Without changing code much is that any possible way to avoid this?

Answer 1

Fix it!

Any scheme you devise to circumvent fixing it will be worse in the long run.

Answer 2

There is no way to avoid this as the java.io.File API is system-dependent. You have to use the right case when manipulating files on Linux/Unix. Actually, my advice/solution would be to follow strict and portable conventions during development on Windows (e.g. use lower case filenames only or, better, use the exact file name when accessing it programmatically). To be honest, I don't understand why you are trying to load Abc.txt when the filename is abc.txt. This is a bad habit (taught by spending too much time on Windows) rather than a Linux/Unix problem.
