java.io.FileNotFoundException on an existing file

Question

I am getting this error when I try to open a file:

java.io.FileNotFoundException: D:\\Portable%20Programs\\Android%20Development\\workspace3\\XXX-desktop\\bin\\W         


        

Answer 1

Try leaving out the %20, and use normal spaces instead. Also, you're using backslashes, in your code if you're using backslashes make sure you escape them first.

Answer 2

The preferred way to convert a file: URL into an actual File is this:

File file = new File(url.toURI());

This takes care of all checks and quoting/escaping.

Using getPath() instead will leave these odd bits up to you.

Answer 3

You need to unescape the %20 to spaces. e.g.:

fileLocation = new String(
    Main.class.getProtectionDomain().getCodeSource().getLocation().getPath())
    .replaceAll("%20", " ");

Answer 4

Here is the solution for that , this will work only after JDK1.5 ,

try { f = new File("somePath".toURI().getPath()); } catch(Exception e) {}

Answer 5

The confirmed solution is quite old and even though it works for this particular case it is far more convenient to use URLDecoder, because %20 is only one encoded character, but in your path there can be whole lot of different encoded characters.

fileLocation = URLDecoder.decode(Main.class.getProtectionDomain().getCodeSource().getLocation().getPath(), "UTF-8");
