RE: Main class directory

The file path and class path are two distinct concepts. Keep in mind what
you are trying to do will fail if your classes are in a jar file; the file
system doesn't recognize a jar as a "file system" - it's just a single file,
so it can't look inside to find individual files.

The way to do what you want is to use getResource() method of Class. Ie,

URL someObject.getClass().getResource(com.myPacackageList.foo.myFile);

then you can call openStream() on the URL to get an InputStream to your
"file".

Or you could also just call getResourceAsStream() of Class, and get an
InputStream directly.

But the key here is you won't be able to work with a File object, you'll
have an InputStream, but that is something you can work with.

Again, if your file is part of a jar archive, it's not accessible by any
file-system calls.
